Participants

Reaction Steps

A solution of 4-(1-bromo-2-oxopropyl)benzonitrile (1 g, 4 mmol) in n-butanol (3 ml) was added in a single portion to a hot (110° C.), stirred solution of 2-aminothiazole in n-butanol (3 ml). After refluxing for 2 hours, triethylamine (0.5 ml, 4 mmol) was added and heating was resumed for a further 2 hours. All volatiles were evaporated and the residue was chromatographed on silica gel, eluting with ethyl acetate:hexane:diethylamine (5:14:1) to afford an off-white solid (0.34 g, 35%), m.p. 88°-91° C.
