実験手順

To 700 ml of water containing 80 g (2.0 mole) of sodium hydroxide is added 85 g (0.27 mole) of N-ethyl-3,6-carbazolediol diacetate. The reaction mixture is heated for one hour then acidified with 3N hydrochloric acid to give N-ethyl-3,6-carbazolediol which is recrystallized from ethanol-water. M.P. 190°-200°C (dec.).
