Versuchsvorschrift
A suspension of N-(4-nitrostyrylsulfonyl)benzamide (14.9 g., 0.045 mole) in 500 ml. of dry benzene is refluxed and stirred with phosphorus pentachloride (10.4 g., 0.05 mole) for 8 hr. The reaction mixture after standing overnight at 25° C. provides 8.2 g. of solid, m.p. 158°-166° C. Concentration of the mother liquor to about 100 ml. provides an additional 2.5 g. of solid, m.p. 158°-161° C. The combined crude solid crystallized from ethyl acetate affords analytically pure N-(4-nitrostyrylsulfonyl)benzimidoyl chloride, m.p. 168°-175° C.
