Procedure

2-Ethyl-4-methylthiazole (0.5 g, 3.93 mmole), 2-bromo-1-phenyl-1-ethanone (0.782 g, 3.93 mmole), and acetonitrile (0.25 mL) were heated in an oil bath at 110 C. for 3 hr, then cooled, dissolved in acetonitrile (4 mL), and diluted with ether (4 mL). After storage at 4 C. overnight, the crystals which separated were filtered out and recrystalized from acetonitrile/ether to give 0.765 g of the title compound, mp 126-128.
