The product from Example 61A (7.19 g, 37.4 mmoles) in THF (30 mL) was treated with 4N NaOH (19 mL, 75 mmoles) and MeOH (5 mL). After one hour, the reaction mixture was concentrated under reduced pressure. The residue was dissolved in ethyl acetate, washed with aqueous NH4Cl, brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure to provide the title compound without further purification.
