Compound 27b (1.22 mmol, 340 mg) was combined with LiOH (4.9 mmol, 118 mg) in 3 mL of THF, 3 mL of MeOH, and 3 mL of water. The mixture was stirred at room temperature for 4 h and was then combined with 15% aqueous citric acid and extracted with EtOAc. The extracts were washed with water and brine, dried over Na2SO4, and concentrated under vacuum to give 288 mg of 27c.
