Reaction Steps
A mixture of compound 35c (340 mg, 1.18 mmol) and LiOH (114 mg, 4.74 mmol) in THF/MeOH/H2O (3/3/3 mL) was stirred for 4 h. A 15% citric acid solution (10 mL) was added. The mixture was then extracted with EtOAc (3×). The combined organic extracts were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The resultant residue, compound 35d (230 mg) was dried under reduced pressure for 18 h and used without further purification.
