Participants

Reaction Steps

A mixture of Example 205A (0.52 g, 1.18 mmol) and LiOH (0.144 g, 6.0 mmol) in 20 mL of THF and 20 mL of H2O was heated under reflux overnight. After the solution cooled to room temperature, the solution was neutralized with 10% HCl, and extracted with ethyl acetate. The organic layer was washed with brine, dried (MgSO4), filtrated and concentrated under vacuum to give the title compound.
