Procedure

A solution of 527 mg (1.40 mmol) of the compound from Example 103A in 9.6 ml of dichloromethane was admixed at RT with 9.4 ml (37 mmol) of 4M hydrogen chloride in dioxane and stirred for 1 h. Then all of the volatile constituents were removed on a rotary evaporator. Drying of the residue in an HV gave 437 mg (94% of theory) of the title compound.
