실험 절차

30.1 g (0.1 mole) of 4-(2,6-dichloroanilino)-3-thiophenacetamide are warmed to 100° in 135 ml of concentrated sulfuric acid and 49 ml of water for 3 hours. The mixture is poured onto ice, and the precipitate of 4-(2,6-dichloroanilino)-3-thiophenacetic acid which has formed in filtered off. The precipitate is boiled up with diisopropyl ether and dried; it then melts at 179° to 180°.
