Reaktionsschritte

A solution of (2,3-dimethylphenyl)(I-trityl-1H imidazol-5-yl)methanone (450 mg, 1.01 mmol) in dichloromethane (25 mL) at room temperature was treated with benzyl magnesium bromide (1.51 mmol) and allowed to react at room temperature and the reaction mixture was then stirred at room temperature for 5 hours. The mixture was quenched with water (10 mL) and a sat. solution of ammonium chloride (10 mL). The residue was isolated in a typical aqueous to give 1-(2,3-dimethylphenyl)-2-phenyl-1-(1-trityl-1H-imidazol-5-yl)ethanol (Intermediate 8) crude, which was taken to the next step without any purification.
