Versuchsvorschrift

A mixture of ethyl 2-methoxy-6-methylbenzoate (5.0 g, 25 mmol), water (10 ml), methanol (40 ml) and sodium hydroxide (2.1 g, 50 mmol) is heated under reflux with stirring. The reaction mixture is diluted with water (150 ml) and acidified with concentrated hydrochloric acid. The solid material is collected by filtration, washed with water and dried yielding dark yellow crystals, 2.1 g, mp 136° C.
