Methanesulfonyl chloride → 2-(4-Fluorophenyl)-4-(3-methanesulfonyloxyphenyl)-5-methoxypyrimidine

Participants

Reaction Steps

1.2 g of 2-(4-fluorophenyl)-4-(3-hydroxyphenyl)-5-methoxypyrimidine and 0.57 g of methanesulfonyl chloride were added to 10 ml of pyridine, and the resulting mixture was stirred for 3 hours at room temperature. After completion of the reaction, ice-cold water was added to the 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 2-(4-fluorophenyl)-4-(3-methanesulfonyloxyphenyl)-5-methoxypyrimidine (Compound 54).
