Reaction Steps
2-Methyl-6(2-Phthalimidoethoxy)isoquinolinium bromide (900 mg.) and hydrazine hydrate (0.3 g.) in ethanol (50 ml) were heated under reflux for 2 hr. The mixture was cooled and the precipitated hydrazide filtered off. Addition of ether to the filtrate gave a solid which was recrystallised from acetonitrile and had m.p. 173°-176°.
