2-Imino-3-(p-aminosulfonylbenzene)-4-thiazolidon was obtained from p-chloroacet-aminobenzenesulfonamide and potassium thiocyanate, and its heating with hydrochloric acid under a pressure resulted in the formation of ammonium p-aminosulfonylbenzene-dithiocarbamate. The latter yielded with sodium chloroacetate 2-thio-3-(p-aminosulfonylbenzene)-4-thiazolidone. By the condensation of 4-thiazolidones, possessing imino, sulfur, or oxygen in the 2-position, and p-acetaminobenzaldehyde, 2-imino, 2-thio, or 2-oxo derivatives of 5-acetaminobenzal-4-thiazolidones were obtained.
