Amphetamine Synthesis: Comprehensive Methods and Schemes

Comprehensive Guide to Amphetamine: Synthesis, Effects, and Legal Aspects

Amphetamine, a potent central nervous system stimulant, has garnered attention for its synthesis methods, effects, and legal implications. In this comprehensive guide, we will delve deeper into these aspects, providing valuable insights into the synthesis of amphetamine, its pharmacology, clinical applications, and the legal landscape surrounding its use and production.

Part 1: Synthesis of Amphetamine

Amphetamine can be synthesized using various methods. While we've touched on one common procedure earlier, here we'll explore another prominent synthesis method - the Leuckart reaction.

Leuckart Reaction

  1. Precursor Selection: In the Leuckart reaction, the precursor of choice is phenylacetone (also known as phenyl-2-propanone or P2P).
  2. Chemical Reactions:
  • Formamide: Formamide is used as a reaction solvent, and ammonium formate acts as the formyl group donor.
  • Reduction: The formyl group from formamide is transferred to P2P through a reductive amination process, yielding amphetamine.
  1.   Reagents and Equipment:
  • Phenylacetone (P2P): The starting material.
  • Formamide and Ammonium Formate: As reagents.
  • Heating Apparatus: Controlled heating is essential.
  • Condenser and Collection Flask: To collect the volatile amphetamine.
  1.   Reaction Conditions: The Leuckart reaction typically occurs under elevated temperatures and controlled pH conditions.

Part 2: Pharmacokinetics and Pharmacodynamics

Understanding how amphetamine interacts with the body is crucial for comprehending its effects and risks.


Absorption: Amphetamine can be absorbed through multiple routes, including oral, nasal, and intravenous administration.

Distribution: It rapidly disseminates throughout the body due to its lipophilic nature and can cross the blood-brain barrier.

Metabolism: Metabolism primarily takes place in the liver via the cytochrome P450 system.

Excretion: The kidneys excrete amphetamine and its metabolites.


  • Mechanism of Action: Amphetamine's primary mode of action involves enhancing the release and blocking the reuptake of neurotransmitters like dopamine and norepinephrine, resulting in increased wakefulness and focus.
  • Effects: Amphetamine induces effects such as heightened alertness, improved concentration, and increased energy.
  • Duration of Action: The duration of amphetamine's effects varies based on the formulation, but they typically last several hours.

Part 3: Clinical Applications, Dosages, and Administration

Amphetamine has a range of clinical applications, especially in the field of mental health.

Clinical Applications

  • Attention Deficit Hyperactivity Disorder (ADHD): Amphetamine-based medications like Adderall and Dexedrine are commonly prescribed to manage ADHD symptoms, improving focus and impulse control.
  • Narcolepsy: Amphetamine can alleviate the excessive daytime sleepiness associated with narcolepsy, enhancing wakefulness.

Dosages and Administration

  • Dosage: The dosage of amphetamine-based medications varies depending on the individual's condition and response to treatment. Medical guidance is crucial for determining the appropriate dosage.
  • Administration: Amphetamine medications are typically administered orally, available in tablet or capsule form, and should be taken as directed by a healthcare provider.

Part 4: Legal Considerations

The legal status of amphetamine is a significant aspect to consider due to its potential for misuse.

Legal Status

  • Controlled Substance: In most countries, amphetamine is classified as a controlled substance due to its potential for abuse and dependence.
  • Prescription Requirements: Medical use of amphetamine requires a prescription from a licensed healthcare provider, and its distribution and possession are regulated by strict laws.


Amphetamine's synthesis, pharmacology, clinical applications, and legal considerations are multifaceted. This comprehensive guide offers insights into different aspects of amphetamine, highlighting its diverse uses while emphasizing the importance of responsible use and adherence to legal regulations. Whether you're a researcher or an individual seeking medical guidance, this guide provides valuable information about amphetamine.
