Procedure

To a solution of 0.294 g (0.52 mmol) of the product of Example 60 dissolved in 3.0 mL of methanol was added 1.0 mL of a 5.0N aqueous solution of sodium hydroxide. The reaction mixture was magnetically stirred at 60° C. After 3 hours TLC analysis (CHCl3 --MeOH--NH4OH 80:15:1) indicated complete hydrolysis of the ester. The reaction was cooled to room temperature, adjusted to pH=5 with dropwise addition of 1.0N HCl, then partitioned between EtOAc and water. The organic layer was separated, washed with saturated aqueous NaCl, dried (MgSO4), filtered and evaporated. The residue was dried in vacuo to afford 0.238 g (83%) of the title compound as an amorphous powder.
