Reaction Steps

One drop of 96% sulfuric acid was added to a mixture of 1.2 g of 2-(4-fluorophenyl)-4-(3-hydroxyphenyl)-5-methoxypyrimidine and 0.5 g of acetic anhydride, and the resulting mixture was stirred for 20 hours at room temperature. After completion of the reaction, ice-cold water was added to mixture. Subsequently, the mixture was extracted with ethyl acetate. The solvent was evaporated off, and the residue was purified by column chromatography on silica gel thereby obtaining 1.0 g of 2-(4-fluorophenyl)-4-(3-acetoxyphenyl)-5-methoxypyrimidine (Compound 55).
