Procedure

To a stirred solution of 28.8 (0.070 g, 0.13 mmol) in THF (2 mL, 0.2 mmol) and EtOH (2 mL, 0.2 mmol) at 23° C. was added a solution of 1 M sodium hydroxide (1.00 mL, 1.0 mmol). The resulting mixture was stirred for 18 hours. The reaction was then concentrated in vacuo. 1 N HCl was added to bring the pH to 1, and the resulting mixture was extracted with EtOAc, dried over MgSO4, filtered, and concentrated. The resulting product was purified by silica gel flash chromatography (0-20% EtOAc/hexane) to afford compound 28 (44 mg, 67% yield) as a colorless oil. MS ESI (neg.) m/e: 979.5 (2M−H)+, 489.2 (M−H)+.
