Reaction Steps

1-(4,5-Dimethyl-2-thiazolyl)ethyl acetate (1.28 g, 6.4 mmole), 2-bromo-1-phenyl-1-ethanone (1.28 g, 6.4 mmole), and acetonitrile (0.5 mL) were heated at 105 C. with stirring for 3.5 hr. The mixture was diluted with water (60 mL), filtered with water washes (20 mL), and the filtrate was extracted with ether (30 mL). The aqueous phase was evaporated to dryness in vacuo yielding 1.8 g crude product, which was dissolved in acetonitrile, diluted with ether, and stored at room temp. for several days to produce needle-like crystals which were recrystallized from methanol/acetonitrile/ether to give 0.57 g of the title compound, mp 236 C. (dec.).
