Procedure

1-Methylcyclopropylamine hydrochloride (J. Org. Chem., 1989, Vol. 54, p. 1815) (1.89 g) was added to dichloromethane (20 ml) containing 4-(2-methane-sulfonyloxyethyl)-5-methanesulfonyloxymethylthiazole (4.46 g) under ice cooling, and the mixture was stirred overnight at room temperature. 1-Methylcyclopropylamine hydrochloride (1.89 g) was additionally added, and the mixture was stirred for 20 hours at room temperature and 5 hours under refluxing. Dichloromethane and water were added to the reaction mixture to separate an organic layer. The organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by column chromatography on silica gel (methanol:dichloromethane=1:49) to obtain the title compound (944 mg) as a pale yellow oil.
