4-Amino-3-methylbenzenesulfonamide

A mixture of N-(2-methyl-4-sulfamoylphenyl)acetamide (5.1 g, 22.3 mmol), HCl (2 N, 76.5 ml) and EtOH (100 ml) was refluxed overnight. Then the mixture was neutralized with Na2CO3 (aq) to pH = 8. The mixture was extracted with EA (80 mL x 4), dried over Na2SO4, and concentrated to obtain 4-amino-3-methylbenzenesulfonamide as a pale solid (4.9 g, yield 100percent).Compound 27-6 (0455) A mixture of 27-5 (5.1 g, 22.3 mmol), HCl (2 N, 76.5 ml) and EtOH (100 ml) was refluxed overnight. Then the mixture was neutralized with NaA round-bottom flask was equipped with a stir bar, a reflux condenser and nitrogen on demand. Into the flask were placed sulfonamide 465 (8.4 g, 36.80 mmol), ethyl alcohol (200 mL) and 2N hydrochloric acid (128 mL). The resulting mixture was allowed to heat to reflux overnight, after which time it was allowed to cool to RT and was neutralized with saturated, aqueous sodium bicarbonate. It was then poured into a separatory funnel containing water and ethyl acetate, the organic layer was collected, washed with water, brine, dried over MgSO
