Reaction Steps

A solution of 3-(3-chloropropyl)-4-chloro-8-methoxyquinoline (6.4 g, 23.6 mmol) and 2-methylaniline (5.0 ml, 47.2 mmol) in ethanol (250 ml) was heated at reflux for 4 days, then cooled and evaporated. Dichloromethane and aqueous sodium bicarbonate solution were added, and the organic layer washed with water, dried and evaporated. Chromatography (silica gel, 1% methanolic ammonia in dichloromethane) followed by crystallisation from ethyl acetate gave 1-(2-methylphenyl)-7-methoxy-1,2,3,4-tetrahydropyridino-[3,2-c]quinoline (1.92 g, 27%), m.p. 160°-161°.
