meth hypo synthesis

Hi wonderful people 👋 Can anyone help me with a solution on how to make hypophosphorus acid and/or anything else that one can use in the Ephedrine-Iodine-hypophosphorus acid synthesis? Without needing to have red phosphorus on hand. Also are there any other names this acid can go by that aren’t...

This method describes how to turn racemic ephedrine hydrochloride to methamphetamine via relatively simple reaction with iodine (I2) and hypophosphorous acid (H3PO2). https://bbgate.com/threads/methamphetamine-synthesis-from-ephedrine-by-using-i2-and-h3po2.10423/#post-56705
