Procedure

The compound of example 1 (79.4 g) was suspended in isopropanol containing 2.1% of HCl (3700 ml) and refluxed for 2 hours with stirring. The reaction mixture was then cooled to 0° C. and a first crop (61 g) of the compound of the title which crystallized out was recovered by filtration. A second crop (9 g) was obtained by concentrating the mother liquors to a small volume. M.p. 220°-223° C. with decomposition.
