p-Bromochlorobenzene → (4-chlorophenyl)[4-(1H-imidazol-1-yl)phenyl]methanol

참여 물질

반응 단계

A Grignard reagent which is prepared by reacting 1.9 g of magnesium with 15 g of p-chlorobromobenzene in 40 ml of ether is added to a suspension of 6.2 g of 4-(1-imidazolyl)benzaldehyde in 70 ml of ether at 0° C. After the mixture is stirred at room temperature for an hour, the reaction mixture is poured into an aqueous ammonium chloride solution with caution. The mixture is extracted with chloroform and the chloroform is distilled off. The residue is purified column-chromatographically and recrystallized from toluene to give 8.6 g of α-(4-chlorophenyl)-4-(1-imidazolyl)benzenemethanol as white crystals, melting at 148.5°-149.5° C.
