Versuchsvorschrift

3-(3,4-Dichlorophenyl)-4-[2-(3,5-dimethylbenzoyl)imidazol-1-yl]butan-1-ol (0.63 g) (see Preparation 47) and triethylamine (0.20 g) were dissolved in dichloromethane (12 ml), cooled in an ice-bath and methanesulphonyl chloride (0.19 g) added. The mixture was stirred for 30 minutes, dichloromethane (35 ml) added and the solution washed sequentially with water (2×30 ml) and brine (30 ml). The organic phase was dried over anhydrous sodium sulphate and the solvent removed under reduced pressure. The residue was dissolved in acetonitrile and the solvent removed under reduced pressure to give 1-methanesulphonyloxy-3-(3,4-dichlorophenyl)-4-[2-(3,5-dimethylbenzoyl)imidazol-1-yl]-butane (0.72 g) as an oil.
