Reaktionsschritte

In a flask were placed 4.0 g (0.014 mole) of the benzoate derivative obtained and 18 ml of ethanol and while stirring the mixture at room temperature, an aqueous solution composed of 2.0 g (0.36 mole) of potassium hydroxide and 20 ml of water was added to the mixture. After stirring the mixture for 24 hours at 40° C. Twenty (20) ml of water was added to the mixture followed by ice-cooled. When the reaction mixture was acidified with concentrated hydrochloric acid, white crystals formed. The crystals were recovered by filtration, washed with water, and dried. Thus, 3.2 g (yield 89.3%) of the desired product could be obtained. The melting point was 165°-166° C.
