Procedure

7.80 g (21.4 mmol) of the compound from example 4A are dissolved in 4N hydrogen chloride solution in dioxane (80 ml). After a few minutes, precipitate formation commences. The mixture is stirred for a further 1 h at RT, and the solid is filtered off with suction and washed with diethyl ether. After drying in vacuo, 5.96 g (93% of th.) of the product are obtained.
