Procedure
A solution of 1-hydrazino-7-methoxyisoquinoline in excess trifluoroacetic acid was allowed to reflux for 2 hours. Excess acid was removed in vacuo and the residue was slurried in water and treated with sodium bicarbonate solution. The solid was removed by filtration and recrystallized from cyclohexane to give the product in a yield of 70%; m.p. 152°-154°C.
