Reaction Conditions

Reaction Steps

To a stirred solution of 4-(4-fluoro-phenyl)-2-(4-iodo-imidazol-1-yl)-6-trifluoromethyl-pyrimidine (Example E.79) (0.87 g, 2.0 mmol) in THF (14 ml) was added at 0° C. iso-propylmagnesium chloride lithium chloride (1M in THF, 2.44 ml, 2.44 mmol). The reaction mixture was allowed to stir for 15 min at 0° C., tributyltin chloride (0.87 g, 2.67 mmol) was added, the reaction mixture was stirred at room temperature for 16 h, poured into saturated ammonium chloride solution (30 ml) and extracted with ethyl acetate (2×50 ml). The combined organic layers were washed with brine (30 ml), dried (MgSO4) and evaporated. The crude product was further purified by flash chromatography on silica gel (ethylacetate/heptane) to yield the title compound (0.69 g, 58%) as a light yellow oil. MS (ISP) 598.7 [(M+H)+].
