Reaction Steps

To a suspension of 4-(1-(2-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenol (ref hydrogenation below) (60 mg, 180 μmol) and Cs2CO3 (140 mg, 400 μmol) in acetonitrile (2 mL) was added 2-chloropyrimidine (66 mg, 580 μmol). The suspension was then heated to 80° C. in an oil bath. After stirring for 16 hours at 80° C. the suspension was filtered through a plug of silica gel (1 g), which was eluted with EtOAc. The filtrate was concentrated under reduced pressure and purified by flash column chromatography eluting with a gradient from 10% to 30% EtOAc/hexane to afford 2-(4-(1-(2-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)phenoxy)pyrimidine (55 mg, 75% yield) as a white powder. MS(ES): 417 [M+H]+.
