Procedure

To a solution of 0.948 mL cyclopropanemethanol in 13 mL dimethylformamide was added 0.468 g sodium hydride 55% in mineral oil and the reaction mixture was stirred at room temperature for 15 min. The resulting solution was added drop wise to a solution of 2.586 g 2-chloro-4-(4-chloro-phenyl)-5-fluoro-pyrimidine at 0° C. and the mixture was stirred at 0° C. for 30 min. The reaction mixture was partitioned between water and ethyl acetate. The phases were separated and the organic phase was purified by chromatography on silica gel using a gradient of heptane:ethyl acetate=10:90 to 80:20 to yield 2.50 g of the title compound as white solid, MS 295.2 (M+H)+.
