Procedure

A solution of 100 mg (0.20 mmol) of the compound from Example 133A in 2 ml of dichloromethane was admixed with 2 ml of a 4M solution of hydrogen chloride in dioxane, and the mixture was stirred at RT for 2 h. It was diluted with ethyl acetate and admixed with 10% strength aqueous sodium hydrogen carbonate solution. The alkaline aqueous phase was extracted twice with ethyl acetate. The combined organic phases were dried over sodium sulphate and freed from the solvents on a rotary evaporator. The residue was the title compound (53 mg, 92% of theory).
