実験手順

13.0 g of N-(2-methoxyethoxy-phenylsulfonyl)-N'-methylurea are suspended in 200 ml of chlorobenzene. The solution is dried by azeotropic destillation of about 20 ml of the solvent. 7.0 g of phosgen are introduced into the solution within 45 minutes at a temperature of the reaction mixture to dryness yields 11.5 g of 2-methoxyethoxy-phenylsulfonyl-isocyanate in form of a yellowish oil.
