Benzenesulfonyl chloride, 4-chloro-3-nitro- → HCID 24884785, compound

Participants

Reaction Steps

4-Chloro-3-nitrobenzenesulfonyl chloride (0.46 g, 1.8 mmol) was added to a solution of 4-(3-chloro-4-(methylaminomethyl)thiophene-2-carbonyl)benzomorpholine hydrochloride (0.54 g, 1.49 mmol) and triethylamine (0.50 ml, 0.36 g, 3.6 mmol) in dichloromethane (20 ml) while cooling in an ice/water bath. The mixture was allowed to warm to room temperature and stirred for 3 days. The mixture was reduced and chromatographed to afford 4-(3-chloro(N-(4-chloro-3-nitrobenzenesulphonyl)-N-methylaminomethyl)thiophene-2-carbonyl)benzomorpholine (0.61 g, 76%) as a white crystalline solid.
