실험 절차

5-Aminoisoquinoline (8 g.) was dissolved in dry benzene (100 ml) and 0.5 g of dry potassium bicarbonate was added to the solution. A 0.1 mole excess of 3,4-dimethoxybenzoyl chloride was dissolved in dry benzene (50 ml) and this solution was poured into the solution of 5-aminoisoquinoline. A precipitate formed immediately. This was collected by filtration and washed with 10% sodium carbonate solution followed by water. The washings were discarded and the insoluble residue was recrystallized from benzene to yield 11.5 g of 5-(3,4-dimethoxybenzamido)isoquinoline as tan needles, m.p. 193°-194° C.
