A solution of ester 10-4 (10.0 g, 56 mmol), 1N NaOH (84 ml, 84 mmole) and CH3OH (200 ml) was stiffed at ambient temperature for 1.0 h. Concentrated HCl (7.0 ml, 84 mmol) was added followed by concentration. The residue was dissolved in CHCl3, dried (MgSO4) and concentrated to give acid 10-5 as a yellow solid.
