Procedure

1.10 g of the product obtained in Stage 2 above, 3 ml of 6N hydrochloric acid and 8 ml of ethanol are introduced, the mixture is taken to reflux for one hour, cooled down to ambient temperature, neutralized by the addition of sodium hydrogen carbonate, extracted with ethyl acetate. The organic phases are combined, washed with water, dried, filtered and concentrated. After chromatography on silica eluting with methylene chloride-acetone: 9-1, then recrystallization from isopropanol, 470 mg of expected product (white solid) is obtained. M.p.=187° C.
