✦ Synopsis

2-Chlorophenylsulfonyl Isocyanate (VII). A 4.11-g (214 mmole) sample of sulfonamide X was dissolved in 35 ml of chlorobenzene, and traces of water were removed by azeotropic distillation. The mixture was cooled to 100~ 0.85 g (8.6 mmole) of n-butyl isocyanate was added, the mixture was heated to the boiling point, and 5 g (50 mmole) of phosgene was passed into it in the course of i h. The n-butyl isocyanate and solvent were then removed by distillation, and the product was distilled in vacuo to give 4 g (86%) of isocyanate Vllwith bp 160-164~ (14 mm). Mass spectrum: 217 (20) [M] +, 175 (54) [M --NCO] +, iii (i00) [M --SOzNCO] +.

Using the example of the reaction of l,3,5-triazines simultaneously containing trichloromethyl and ethoxycarbonyl substituents with phenylhydrazine, it was shown that the presence of even one ester group leads to ring transformation. Depending on the number of the ester groups in the initial 1,3,5-t
