Procedure

A mixture of Compound 144 (1.0 g) obtained in Example 144, a 4N aqueous solution (8.0 ml) of sodium hydroxide, and ethanol (40 ml) was stirred at room temperature for 4 hours. The solvent was removed and the residue was dissolved in water. Concentrated hydrochloric acid was dropwise added to the solution, and the generated precipitate was collected by filtration, washed with water, and dried to give Compound 145 (0.82 g, 85.9%) as white crystals.
