Water → Benzenesulfonamide, 4-chloro-N-methyl-3-nitro-

참여 물질

반응 단계

To a solution of 4-chloro-3-nitrobenzenesulfonyl chloride (2.0 g, 7.8 mmol) in THF (10 mL) was added excess methylamine (2M solution in THF). The reaction solution was stirred at room temperature for 1 hr. Water was then added and the product was extracted into chloroform. The combined extracts were washed, dried over sodium sulfate, filtered and evaporation to yield 2.3 g of the crude 4-chloro-N-methyl-3-nitrobenzenesulfonamide as an oil. The crude material was used in the subsequent step without further purification.
