Reaktionsschritte

A solution of 1.5 g of 4-methyl-N-[4-(3-nitro-phenyl)-thiazol-2-yl]-benzenesulfonamide in 150 ml of methanol and 70 ml of ethyl acetate was hydrogenated at room temperature after the addition of 0.15 g of palladium on active charcoal (10%). The catalyst was filtered off and the filtrate was concentrated. Crystallization from ethyl acetate/hexane (1:1) yielded 1.1 g of N-[4-(3-amino-phenyl)-thiazol-2-yl]-4-methyl-benzenesulfonamide as a colorless solid.
