実験手順

To a solution of 4-bromo-3-methylbenzene-1-sulfonyl chloride (500 mg, 1.86 mmol) and DIEA (0.65 mL, 3.7 mmol) in N,N-dimethylformamide (5 mL) was added methylamine as a 2.0 M solution in methanol. The reaction mixture was allowed to stir at room temperature overnight. The reaction mixture was evaporated to dryness and was dissolved in dichloromethane (3 mL). The solution was washed with 1 N HCl (2×3 mL) and a saturated solution of NaHCO3 (3 mL). The organics were dried over Na2SO4 and evaporated to dryness to give 4-bromo-N,3-dimethylbenzenesulfonamide (340 mg).
