Procedure

4 g of product obtained in stage A are heated to reflux for 1 hour with 4 g of sodium acetate in 80 cm3 of acetic anhydride. The mixture is cooled to room temperature and evaporated to dryness, the residue is taken up in 60 cm3 of water, filtered and dried and 3.5 g of expected product are obtained. After crystallization in isopropanol, 2.3 g of product are obtained. M.p. 164°-165° C.
