실험 절차

2-Methyl-3-(2-chloroethyl)-4-chloro-8-methoxyquinoline (54 g, 0.2 mol), o-methylaniline hydrochloride (28.7 g, 0.2 mol) and 1-butanol (500 ml) were heated to 17° C. in a pressure vessel for 10 hours, then the solvent evaporated. Conversion to free base and chromatography (silica gel, 2% methanolic ammonia in dichloromethane) gave 1-(2-methylphenyl)-4-methyl-6-methoxy-2,3-dihydropyrrolo[3,2-c]quinoline in the early fractions. Later fractions were recrystallised from ethyl acetate to yield 1-(2-methylphenyl)-4-methyl-6-hydroxy-2,3-dihydropyrrolo[3,2-c]quinoline, m.p. 144°-146°.
