実験手順
A solution of 17.5 g of 2-(1,2-dichlorovinyloxy)phenylsulfonyl-chloride in 150 ml of methylene chloride is added slowly to a mixture of 30 ml of methylene chloride, 50 ml of water and 50 ml of 30% aqueous ammonia. The reaction mixture is stirred for 6 hours at a temperature of 20°-25° C. The organic phase is washed with water, dried over sodium sulfate and evaporated to a volume of 40 ml. The crystallised 2-(1,2-dichlorovinyloxy)phenylsulfonamide is separated and dried. Yield: 12.5 g, m.p. 147°-149° C.
