실험 절차

A mixture of ethyl 6-methyl-2-methoxybenzoate (642.0 g, 3.3 mol), water (2.5 l), ethanol (4.0 l) and sodium hydroxide (270 g, 6.6 mol) is heated under reflux with stirring for 20 hours. Subsequently, ethanol is distilled off and the reaction mixture is diluted with water, acidified with concentrated hydrochloric acid. The solid material is collected by vacuum filtration, washed with water and dried yielding off-white crystals, 460.0 g (83.9%).
