Participants

Reaction Steps

2-Methyl-3-(2-chloroethyl)-4-chloroquinoline hydrochloride (5.53 g, 20 mmol) and 4-methoxy-2-methylaniline (5.15 ml, 40 mmol) in ethanol (100 ml)were heated at 170° C. in a pressure vessel for 24 hours, then the solvent evaporated, the crude product taken up in dichloromethane, washed with aqueous sodium bicarbonate, dried and evaporated. Chromatography (silica gel, 2% methanolic ammonia in dichloromethane) and recrystallisation from aqueous methanol gave 1-(4-methoxy-2-methylphenyl)-4-methyl-2,3-dihydropyrrolo[3,2-c]quinoline (2.04 g, 22 %), m.p. 115°-117°.
