Procedure

Sodium hydride (60% in mineral oil, 23 mg, 0.58 mmol) was added to a solution of (2-fluoropyridin-3-yl)(1H-imidazol-4-yl)methanone (100 mg, 0.52 mmol) in tetrahydrofuran (3 ml), cooled to 0° C. The reaction mixture was then stirred for 30 minutes. Benzyl bromide (0.062 ml, 0.52 mmol) was added and the mixture was warmed up to room temperature. The reaction mixture was stirred for 18 hours, diluted with ethyl acetate and washed with a saturated aqueous solution of sodium bicarbonate and brine. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography to afford the title compound (100 mg, 68% yield).
