Reaction Conditions

Reaction Steps

The product from Step 1 (600 mg, 2.13 mmol) was dissolved in methanol (15 mL), NaOH solution (5 mL, 2.5 M) was added, and this reaction mixture was heated to 60° C. for 18 h. The reaction mixture was concentrated, and then poured into EtOAc (20 mL) and water (5 mL). The aqueous layer was acidified to pH<3 with 6N HCl, and extracted with EtOAc (50 mL). The organic phase was washed with brine, dried over Na2SO4, filtered and concentrated. The residue was triturated with 5% ether/hexanes to afford the title compound (312 mg, 55%). MS (ES+) m/e 268 [M+H]+.
