To a solution of {2-bromo-4-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)-3,4-dihydro-2H-pyrrol-5-yl]phenyl}methanol (0.95 g) and triethylamine (0.41 g) in dichloromethane was added methanesulfonyl chloride (0.35 g) gradually, and the mixture was stirred for 2 hours at room temperature. The reaction liquor was washed with water and a saturated aqueous brine, subsequently dried over magnesium sulfate. After filtering the reaction mixture, the solvent was distilled off under reduced pressure, to obtain 2-bromo-4-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)-3,4-dihydro-2H-pyrrol-5-yl]-benzyl methanesulfonate (1.0 g).
