Reaction Steps

A solution of thioformamide (prepared according to A1-Razzar et al. U.S. Pat, No. 5,559158; 1.2 g, 20 mmol) and 2-chloro-4-methyl-3-oxopentanoic acid ethyl ester (2.0 g, 10 mmol) in ethanol (20 mL) was heated at reflux for 17 h. The reaction mixture was evaporated to dryness and the residue was chromatographed over silica gel (5-20% ethyl acetate/hexanes) to give 4-(1-methylethyl)thiazole-5-carboxylic acid ethyl ester (720 mg, 36% yield).
