Procedure
A mixture of 1.0 g. of the ester obtained in step C and 0.1 powdered porous plate is heated, with stirring, in an oil bath at 210° C. under nitrogen, then dissolved in benzene and ether, filtered and extracted with sodium bicarbonate solution. The aqueous solution is filtered by suction to remove ether, neutralized with acetic acid, then acidified weakly with dilute hydrochloric acid. The crude product is then recrystallized from aqueous ethanol and dried in vacuo.
