Reaction Steps

Methyl 4-imidazolecarboxylate 0.80 g (6.34 mmol) was placed in a flask and under argon 50 ml (25 mmol) of a 0.5M 3,5-difluorophenylmagnesium bromide solution in tetrahydrofuran were added. The mixture was refluxed for 2 hours and then most of the solvent was evaporated. Water was added with cooling, and the mixture was extracted twice with ethyl acetate. The combined organic extracts were concentrated and the residue was purified by flash chromatography (silica gel, heptane/ethyl acetate 8:2) to yield 1.5 g (73%) of bis-(3,5-difluoro-phenyl)-(1H-imidazol-4-yl)-methanol as a white solid; MS (ISP): 305.1 ((M-OH)+); 323.4 ((M+H)+.).
