A mixture of 0.037 g (0.1 mmole) of 4-(3-chloro-phenyl)-2-(6-hydroxy-benzoimidazol-1-yl)-thiazole-5-carboxylic acid amide (I.25d), 0.5 mL of dimethylformamide, 0.069 g (0.5 mmole) of potassium carbonate, 0.001 g of potassium iodide and 0.012 mL (0.15 mmole) of 2-chloromethyl-oxirane was heated at 100 degrees for 3 hours. The mixture was concentrated under reduced pressure, diluted with 20 mL of water and the resulting precipitate collected by filtration. The solid was triturated with diethyl ether to give 0.032 g of 4-(3-chloro-phenyl)-2-(6-oxiranylmethoxy-benzoimidazol-1-yl)-thiazole-5-carboxylic acid amide (I.39a) as a white solid.
