The mixture was stirred at room temperature for 4 hours. Pyridine hydrochloride was filtered rapidly and N-methylbenzenesulfonamide (3.5 g, 0.02 mol) was added. The mixture was cooled in an ice-water bath and triethylamine (2.2 g, 0.022 mol) was added dropwise. After the complete addition of the amine the mixture was stirred at room temperature for an additional half hour.
