Participants

Reaction Steps

1.79 g of commercially available 4-bromo-benzenesulfonyl chloride were dissolved in 35 ml dichloromethane. Then 1.85 g 5-(4-trifluoromethyl-phenyl)-2,3-dihydro-1H-indole hydrochloride were added followed by 2.14 ml triethylamine. The mixture was stirred at room temperature for fifteen minutes. Then 100 ml of dichloromethane were added, the mixture washed with 40 ml water and brine and then dried over MgSO4. The solvent was removed in vacuo to obtain 2.48 g crude 1-(4-bromo-3-chloro-benzenesulfonyl)-5-(4-trifluoromethyl-phenyl)-2,3-dihydro-1H-indole. This material was used without further purification.
