To a solution of 104 mg (0.5 mmoles) of 2,3-dichloro-4-ethoxycarbonylpyrrole in 5 ml of dry N,N-dimethylformamide were added 303 mg (0.5 mmoles) of 2,3,3-triiodoallyl-p-toluenesulfonate and 0.07 ml (0.5 mmoles) of triethylamine and the resulting mixture was heated at 60° C. for 2 hours. The reaction mixture was cooled, 10 ml of cold water were added with stirring thereto and the so separated crystalline substance, 1-(2',3',3'-triiodoallyl)-2,3-dichloro-4-ethyoxycarbonylpyrrole, was recovered by filtration, washed with water and then dried. Yield 281 mg (90%), mp 117°-119° C.
