Reaction Steps

To a stirring solution of ethyl 2-(acetylamino)-4-(chloromethyl)-1,3-thiazole-5-carboxylate (1.0 g, 3.81 mmol) in N,N-dimethylformamide (20 mL) was added triphenylphosphine (1.2 g, 4.57 mmol) at room temperature. The resultant mixture was stirred at 65° C. for 5 hours. To the mixture was added potassium tert-butoxide (555 mg, 4.95 mmol) at 5° C., and the resultant mixture was stirred at 5° C. for 30 minutes p-Nitrobenzaldehyde (805 mg, 5.33 mmol) was added at 5° C. After stirring for 1 hour at room temperature, the reaction was quenched with water, and the mixture was filtered to give the title compound (1.0 g, 72.7%) as a yellow solid.
