실험 절차
A mixture of 1A (20.2 g, 0.078 mol), ethanol (150 ml) and an aqueous sodium hydroxide (12 g, 0.3 mol in 100 ml water) is heated under reflux with stirring for 16 hours. The reaction mixture is cooled to room temperature, diluted with water (600 ml) and acidified with concentrated hydrochloric acid. The precipitate is collected and washed with water yielding 18.45 g (100%) white crystals with a melting point of 163-165° C.
