Reaction Steps

0.20 g 4-Methoxy-7-morpholin-4-yl-benzothiazole-2-carboxylic acid and 0.125 g 1,1′-carbonyl-diimidazole in 1 ml DMF were stirred at room temperature for 1 hour. 0.13 g 2-aminoacetophenone hydrochloride and 0.08 g triethylamine were added and stirring was continued for two days at room temperature. 200 ml water was added and the mixture was extracted with ethylacetate. Chromatography on silicagel with ethylacetate/hexane 4:6 yielded 0.18 g (64%) 4-methoxy-7-morpholin-4-yl-benzothiazole-2-carboxylic acid (2-oxo-2-phenyl-ethyl)-amide as a yellow solid; M.p.: 197–200° C.; MS (ISP): m/e=412 (M+H+).
