Process for preparing cotarnine

A process for preparing cotarnine is provided which comprises oxidizing the amino group of a tetrahydroisoquinoline compound represented by the following formula (I): STR1 to convert said compound into a dihydroisoquinolinium salt represented by the following formula (II): STR2 wherein A- represents an anion, and then hydrolyzing said dihydroisoquinolinium salt.

Benzylamine derivative

There is provided a novel benzylamine derivative of the formula I: STR1 wherein R1 represents a hydrogen atom or a methyl group, X represents a hydrogen atom, a methyl group or a tosyl group, and Y represents a hydrogen atom, a methyl group or STR2 in which R2 and R3 being identical or different from each other represent independently a lower alkyl group.
