反応手順
A solution of 3-butyryl-4-chloro-8-(4-methoxybenzo yloxymethyl)quinoline (2.56 g, 6.4 mmol) and 4-amino-3-methylphenol (1.18 g, 9.6 mmol) in 1,4-dioxan (30 ml) was heated at reflux for 2 hours, then evaporated. Chromatography (silica gel, 1% methanol in dichloromethane) and recyrstallization from ethanol gave 3-butyryl-4-(4-hydroxy-2-methylphenylamino)-8-(4-methoxybenzoyloxymethyl)-quinoline, (2.36 g, 76%), m.p. 171°-175°.
