Procedure

A solution of 1-[4-(2-Amino-4-methyl-thiazol-5-yl)-phenyl]-ethanone (0.57 g, 2.45 mmol) is dissolved in a mixture of THF (10 ml) and dichloromethane (20 ml) and heated in an oil bath set to 50° C. Carbonyldiimidazole is added (0.64 g, 3.92 mmol) and the reaction mixture heated at 50° C. for a further 2 hours in which a pale yellow precipitate forms. After cooling to room temperature the precipitate is filtered, washed with dichloromethane and dried under high vacuum.
