Procedure

To a 2 ml dioxane solution of 87 mg (0.17 mmol) of the compound obtained in Example 49, 0.1 ml (0.4 mmol) of a 4M dioxane hydrochloride solution was added. Ether was added to the resulting solution, and precipitated solids were collected by filtration. The solids were purified by recrystallization (ethanol) to obtain 52.1 mg (56%) of the captioned compound.
