ABSTRACT:
An aniline is converted to a 3-lower hydrocarbonthiooxindole by processes already known in the art and then air oxidized in an inert liquid vehicle in the presence of a base. The inert liquid vehicle advantageously is aprotic and the base is non-nucleophilic. Also, the aprotic liquid vehicle is desirably solvent for the starting 3-lower hydrocarbonthiooxindole and the non-nucleophilic base.
