Question Question about Cumyl-inaca (precursor of SGT)

[batman99]

I currently have Cumyl-inaca in stock, I would like to synthesize a legal product in my country. Does anyone know of other additives besides 1-bromopentane?
Can I replace 1-bromopentane with 5-bromo-1-pentene?

Fluoropentane, there's also fluorobenzene to make the FUB version, which i haven't tried, but from its pharmacological data is VERY powerful.

Something im interested in (and dont know the proper reactant) is attaching a trimethylsilyl group to the end of the tail to make CUMYL-3TMS-PRINACA which ive read is also ridiculously powerful.
