6.8 ml of a 4N solution of hydrogen chloride in dioxane are added to a solution of 0.263 g (0.46 mmol) of the compound from Example 258A in 1 ml of dioxane at 0° C. After 2 h at RT, the reaction solution is concentrated in vacuo and coevaporated with dichloromethane several times. The remaining solid is dried to constant weight under high vacuum.
