실험 절차

A mixture of 0.5 g of 4-(3,4-dichloro-phenyl)-thiazol-2-ylamine hydrobromide with 0.50 g of p-toluenesulfonyl chloride was stirred overnight with 2 ml of pyridine. The resulting, red colored suspension was poured into 30 ml of 1N hydrochloric acid and the solid which thereby separated was filtered off and dissolved in a mixture of 20 ml of ethanol and 20 ml of 2N sodium hydroxide solution. After the addition of 0.4 g of active charcoal the mixture was stirred at room temperature for 30 minutes and subsequently the active charcoal was filtered off. 0.33 g of N-[4-(3,4-dichloro-phenyl)-thiazol-2-yl]-4-methyl-benzenesulfonamide was obtained as colorless crystals upon neutralization with concentrated hydrochloric acid.
