Procedure

To a solution of (2-chloro-6-(1-ethoxyvinyl)pyrimidin-4-yl)methyl methanesulfonate (0.452 g, 1.54 mmol) in benzene (7 mL) were added 3,3,3-trifluoropropan-1-ol (0.264 g, 2.32 mmol), sodium hydroxide (5 M, 0.463 mL, 2.32 mmol) and tetrabutylammonium hydrogen sulfate (0.052 g, 0.15 mmol). The mixture was stirred vigourously over night at room temperature. The mixture was filtered through a short silica plug with magnesium sulfate on top. The filter was washed with EtOAc. The mixture was purified by preparative HPLC to give 2-chloro-4-(1-ethoxyvinyl)-6-((3,3,3-trifluoropropoxy)methyl)pyrimidine 0.055 g 11%).
