To a stirred suspension of sodium hydride (630 mg, 60% dispersion in mineral oil) in tetrahydrofuran (20 ml) at 0° C. was added benzyl alcohol (1.09 ml). The mixture was stirred for 15 minutes then a solution of 4-chloro-2-methylsulfanyl-6-(3-trifluoromethyl-phenyl)-pyrimidine (1.6 g) in tetrahydrofuran (14 ml) was added dropwise. The reaction was allowed to warm to room temperature and stirred for two hours. Solvent was evaporated under reduced pressure and the remaining residue dissolved in dichloromethane (200 ml) and washed with water (2×150 ml). Organics were separated, dried over sodium sulphate and solvent was removed under reduced pressure to yield crude product (2.5 g). Flash chromatography on silica yielded product 4-benzyloxy-2-methylsulfanyl-6-(3-trifluoromethyl-phenyl)-pyrimidine (1.75 g) as a yellow solid.
