実験手順

27.4 g (0.1 mole) of 4-(2,6-dichloroanilino)-3-thiophenmethanol are dissolved in 800 ml of concentrated aqueous hydrochloric acid, and the solution is left to stand for eight hours, poured onto ice and extracted with toluene. The organic phase is washed with sodium bicarbonate solution, dried and concentrated. Recrystallization of the residue from petroleum ether gives 3-(2,6-dichloroanilino)-4-chloromethylthiophen (m. 89° to 92°).
