Procedure

The product of Step A (1.20 g, 5.5 mmol) was suspended in 16.5 mL of 1N NaOH and stirred at room temperature for 1 hour. The pH was adjusted to 4 with 3N HCl and concentrated to near dryness under reduced pressure. The wet residue was suspended in EtOAc and treated with sodium acetate (1.30 g, 18 mmol). The EtOAc layer was dried (Na2SO4), filtered and evaporated under reduced pressure affording 641 mg (61%) of product. 1H-NMR (300 MHz, d6-DMSO) δ 2.18 (s, 3H), 2.46 (s, 6H), 6.35 (d. J=8 Hz, 1H), 6.67 (d. 8 Hz, 1H).
