Procedure

To a solution of 1-ethyl-2-piperazin-1-yl-6-(trifluoromethyl)-1H-indole-3-carbonitrile (32 mg, 0.1 mmol), pyridine (0.1 mL) in dichloromethane (1.0 mL) is added cyclopropanesulfonyl chloride (28 mg, 0.2 mmol) and the mixture is stirred at room temperature overnight. This is then diluted with dichloromethane (5 mL), washed with HCl (2 N, 2×2 mL), water (2×5 mL) and brine (5 mL) and chromatographed over silica gel (dichloromethane/ethyl acetate, 9/1) to provide 2-[4-(cyclopropylsulfonyl)piperazin-1-yl]-1-ethyl-6-(trifluoromethyl)-1H-indole-3-carbonitrile, compound 842 (30 mg, 70%).

Workup

  1. washwashed with HCl (2 N, 2×2 mL), water (2×5 mL) and brine (5 mL)
  2. customchromatographed over silica gel (dichloromethane/ethyl acetate, 9/1)
