Reaction Steps

Methylamine hydrochloride (1057 mg, 15.65 mmol) and triethylamine (3.3 mL, 23.48 mmol) were dissolved in dichloromethane (20 mL) and then 3-bromobenzene-1-sulfonyl chloride (4.0 g, 15.65 mmol) was slowly added. The reaction mixture was stirred at room temperature for 2 hours, diluted with dichloromethane, and washed with brine. The organic layer was dried with magnesium sulfate, filtered with celite, and then concentrated. The resultant target compound (3.5 g, 90% yield) was used in the following reaction without purification.
