実験手順
N-(4-Nitrostyrylsulfonyl)benzimidoyl chloride A mixture of 4-nitrostyrylsulfonamide (18.2 g., 0.08 mole), benzoyl chloride (12.6 g., 0.09 mole) and phosphorus oxychloride (13.8 g., 0.09 mole) is heated at steam bath temperature for 1.5 hr. The reaction mixture diluted with 20 ml of ethyl acetate, cooled and filtered affords 19.0 g (76% yield) of N-(4-nitrostyrylsulfonyl)benzamide, m.p. 192°-195° C., from ethyl acetate-hexane.
