To a solution of methylmagnesium iodide in ether (3 M, 13,7 ml, 41.1 mmol) and ether (40 ml), 1-(3,4-dichloro-phenyl)-1H-imidazole-4-carbaldehyde (2.58 g, 10.7 mmol) was added in portions. THF (50 ml) was then added slowly and stirring was continued for 1 h at reflux. After the addition of aqueous ammonium chloride (saturated, 30 ml), the mixture was extracted with AcOEt. The organic phase was dried (Na2SO4) and evaporated to give 1-[1-(3,4-dichloro-phenyl)-1H-imidazol-4-yl]-ethanol (2.56 g, 93%) as a light brown solid. MS: m/e=257.0 (M+H+).
