Participants

Reaction Steps

The product from Example 197a (4.00 g, 19.3 mmol) in THF (40 mL) was added aqueous LiOH solution (0.91 g, 21.2 mmol dropwise at room temperature over 10 minutes. The mixture was allowed to stir at room temperature for 27 hours and then evaporated. The aqueous residue was diluted with H2O, adjusted to pH 4 with 10% HCl, and then extracted with EtOAc. The extract was washed with brine, dried over MgSO4, filtered and concentrated under vacuum giving the title compound which was purified by washing with cold EtOAc to give the title compound as colorless crystals (2.92 g, 92%).
