Procedure
Hydrogen chloride gas was bubbled into a solution of the product of Example 392A (50 mg, 0.11 mmol) in methanol (10 mL) at 0° C. until saturation. The reaction was stirred at room temperature for 3 hours. The solution was evaporated under reduced pressure to give title compound (quantitative yield).
