Participants

Reaction Steps

To a mixture of [[4-[(7-trifluoromethyl-4-quinolinyl)amino]phenyl]sulfonyl]piperazine (prepared as in Example 9, part D) and triethylamine, in dimethyl formamide, is added dropwise an equimolar quantity of dimethylsulfamoyl chloride. The reaction mixture is stirred at room temperature for 15 to 25 hours and is then partitioned with methylene chloride-aqueous sodium carbonate. The organic phase is dried over sodium sulfate and is concentrated and purified by conventional methods to give 1-(dimethylaminosulfonyl)-4-[[4-[[7-(trifluoromethyl)-4-quinolinyl]amino]phenyl]sulfonyl]piperazine.
