Procedure

A mixture of Compound 90a (3.5 g) obtained in Step A, a 4N aqueous solution (35.0 ml) of sodium hydroxide, and ethanol (150 ml) was stirred at room temperature for 15 hours. The solvent was distilled off and the residue was dissolved in water. Concentrated hydrochloric acid was dropwise added to the solution, and a precipitate was collected by filtration, washed with water, and dried to give Compound 90b (2.38 g, 74.9%) as white crystals.
