Abstract
N-Phenyl-N'-cyano-O-phenylisoureas are prepared from N-cyanodiphenoxyimidocarbonate and an optionally substituted o-phenylenediamine or o-aminophenol. The isoureas are new chemical intermediates especially useful for preparing 2-cyanamido and 2-carbomethoxyaminobenzimidazole and benzoxazole compounds having anthelmintic activity.
