Procedure

Dissolve the compound of Example 91 (50 mg, 0.09 mmol) in ethyl acetate (1 mL), dilute with diethyl ether (5 mL), and immediately place into an ice bath and add 2M HCl in diethyl ether (0.07 mL). Collect the precipitate on filter paper and rinse with diethyl ether. Dry the solid in a vacuum oven overnight at 60° C. to give 19 mg of the title compound (38%): mass spectrum (ion spray): m/z=524 (M+H).
