Abstract
The invention comprises N-p-toluenesulphonyl-N1-(b -methylsulphinylethyl)-urea of the formula CH3,C6H4,SO2,NH,CO,NH ,C2H4,SO,CH3 and its preparation by reacting p-toluenesulphonyl urea with b -methylsulphinylethylamine hydrochloride in a molecular ratio of 1 : 1,1, in dioxane or dimethylformamide, at a temperature of approximately 100 DEG C. The above compound may also be made by other standard methods for the preparation of sulphonyl ureas, by reacting a p-toluenesulphonyl compound CH3,C6H4,SO2X with a compound Y,C2H4,Z1,CH3 wherein Z1 = S or SO (the former being subsequently oxidized to the latter) and X and Y represent radicals capable of forming the urea bridge, e.g. -NCO, -NH2; -NH,CO-Hal, -NH2; -NHCOOAr, -NH2; -NHCONH2, -NH2; -NHCONH Acyl, -NH2; -NHCONH,NO2, -NH2; -NHCONHAr, -NH2; -CON3, -NH2 and -CO,NH,Hal, -NH2; or by reacting a sulphonyl halide (X = halogen) with an isourea ether -NH,C(OR): NH and hydrolysing the resulting sulphonyl isourea ether. Specification 824,218 is referred to.
