Procedure

4-Nitrophenyl chloroformate (1.89 g, 9.38 mmol) was added to a solution of 6-(3,4,5-trifluorophenyl)-1,6-dihydro-2-methoxy-5-acetyl-4-meth-ylpyrimidine (2.80 g, 9.38 mmol) and pyridine (10 mL) in CH2Cl2 (200 mL) at 0-5° C., and the resulting mixture was allowed to warm to room temperature. After 12 h, the solvent was evaporated and the residue was purified by flash chromatography (dichloro-methane/EtOAc, 1/9 to 3/20), giving the desired product as a white powder (4.00 g, 92%).
