1-(3,4-Difluorophenyl)-2,2,2-trifluoroethanol (0.1 g, 0.471 mmol) was treated with NaH (60% in mineral oil, 38 mg, 0.943 mmol) in dry THF (3 ml) for 30 minutes. 2-Amino-4,6-dichloropyrimidine (77 mg, 0.471 mmol) was added and the mixture was stirred at 50° C. for 6 hours. The mixture was quenched with water and extracted with methylenechloride (2×). The organics were combined, washed with water, then brine, dried over MgSO4, and concentrated to give 0.14 g of 4-chloro-6-(1-(3,4-difluorophenyl)-2,2,2-trifluoroethoxy)-pyrimidin-2-amine.
