2.1 g of 2-(2,4-difluorophenyl)-4-(3-trifluoromethylphenyl)-5-methanesulfonylpyrimidine, 0.3 g of sodium methoxide and 20 ml of methanol were added to 120 ml of ethylene glycol dimethyl ether and the resulting mixture was heated under reflux for 5 hours. The solvent was distilled away under reduced pressure. The residue was washed with water and then dried to obtain 1.55 g of 2-(2,4-difluorophenyl)-4-(3-trifluoromethylphenyl)-5-methoxypyrimidine (Compound 77).
