2,2,2-Trifluoroethanol → HCID 86663137, compound

Participants

Reaction Steps

To a mixture of 2.0 ml 2,2,2-trifluoroethanol in 35 mL dry DMF was added 1.1 g sodium hydride was added and the mixture was stirred at room temperature for 15 minutes. The resulting solution was added drop wise at −10° C. to a solution of 7 g 2-chloro-4-(3,4-dichloro-phenyl)-5-fluoro-pyrimidine in 50 mL dry DMF during 39 min. The reaction mixture was then stirred at room temperature for 2 h. The resulting brown mixture was partitioned between water and ethyl acetate, the phases were separated the organic phase was dried over MgSO4 and purified by chromatography on silica gel with a gradient of heptane:dichloromethane=1:1 to dichloromethane to yield 5.575 g (61.81%) of the title compound as light yellow solid, MS 356.9 (M+H)+.
