실험 절차

A suspension containing 1 g of N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-2-nitrobenzenesulfonamide, 0.2 g of 5% palladium on carbon and 50 ml of ethanol was shaken in a Paar apparatus under 40 p.s.i.g. hydrogen at ambient temperature. After one hour, the reaction mixture was filtered and the solids thereby recovered, which contained catalyst and desired product, was stirred with 10% aqueous sodium hydroxide. Filtration of that mixture and acidification of the filtrate with hydrochloric acid to pH 3 caused the desired product to precipitate. After removal by filtration and drying, the desired product melted at 212°-216° and showed infrared absorption peaks at 3200 and 3300 cm-1, consistent for the desired amino-containing compound. Mass spectrometry showed two particles of mass 198 and 123 units, equivalent to aminobenzenesulfonyl isocyanate and 2-amino-4,6-dimethylpyrimidine respectively, as expected for the desired compound.
