Abstract
A process for the preparation of a sulfamidic product having the following formula: that is: 1 for methylbenzenesulfonyl-3 N-butylurea or para-toluenesulfonyl-N-butylurea characterized by starting from the para- toluenesulfonamide transforming it into para-toluenesulfonurea which, by condensation with N-butylurea hydrochloride, provides para-toluenesulfonyl-N-butylureas either in liquid vehicle based on an anhydrous solvent, at reflux temperature, or in dry conditions at a minimum melting temperature of the reaction mass .
