2,5-Dimethoxyaniline → 3-Butyryl-4-(2,5-dimethoxyphenylamino)-8-methylquinoline

Participants

Reaction Steps

3-Butyryl-4-chloro-8-methylquinoline (2.48 g, 10 mmol), 2,5-dimethoxyaniline (3.06 g, 20 mmol) and 1,4-dioxan (10 ml) were stirred at room temperature overnight then heated at reflux for 30 minutes. The hydrochloride salt was filtered off, converted to free base and recrystallised from aqueous ethanol to give 3-butyryl-4-(2,5-dimethoxyphenylamino)-8-methylquinoline (1.07 g), m.p. 115°-116°.
