Reaction Steps
To a solution of 6-(3,4,5-trifluorophenyl)-1,6-dihydro-2-methoxy-5-acetyl-4-methylpyrimidine (2.8 g, 9.38 mmol) and pyridine (10 mL) in CH2Cl2 (200 mL) at 0-5° C. was added 4-nitrophenyl chloroformate (1.886 g, 9.38 mmol) and the mixture was allowed to warm to room temperature. After 12 hours solvent was evaporated and the residue was purified by flash column chromatography (SiO2, dichloromethane/EtOAc, 10%-15%) to obtain the product as a white powder (4.0 g, 92%).
