Reaction Steps

2-Aminothiazole (10.00 g, 99.86 mmole), triethylamine (20.2 g, 200 mmol) and a catalytic amount of 4-(N,N-dimethylamino)pyridine in anhydrous tetrahydrofuran (200 mL) were stirred at 0° C. Methyl chloroformate (18.9 g, 200 mmol) was added slowly to the mixture at 0° C. Then the reaction mixture was stirred at room temperature for several hours. The tetrahydrofuran was evaporated, the residue was dissolved in chloroform, and the resulting solution was washed with water, dried through magnesium sulfate, filtered, and then the solvent was evaporated. The residue was purified by flash chromatography using a gradient of ammoniated methanol in chloroform to give the sub-title compound as a pale yellow solid (17.0 g), m/z 159 (MH+).
