Procedure
A solution of the product of Example 201C (121.8 mg, 0.1603 mmol) in 1,4-dioxane (3 mL) was treated with a solution of lithium hydroxide monohydrate (13.5 mg, 0.3206 mmol) in water (1.5 mL) at ambient temperature, then heated at 70° C. for 30 minutes. The reaction was cooled to room temperature, diluted with ethyl acetate (75 mL) and water (30 mL), adjusted the aqueous pH to 6 with 1N aqueous hydrochloric acid, and separated the layers. The organic phase was washed with water (2×25 mL) and brine (25 mL), dried over anhydrous sodium sulfate, filtered, and concentrated by rotary evaporation in vacuo. Purification of the residue by silica gel flash chromatography with 6% methanol/methylene chloride afforded the title compound as a light yellow solid (66 mg, 77%). 1H NMR (300 MHz, DMSO-d6) δ ppm: 1.34 (d, J=6.99 Hz, 6 H) 3.05-3.39 (m, 1 H) 3.83 (s, 3 H) 5.59 (s, 2 H) 6.64 (d, J=8.46 Hz, 2 H) 6.82 (d, J=8.82 Hz, 1 H) 6.88 (dd, J=7.35, 1.84 Hz, 1 H) 7.14 (d, J=8.46 Hz, 2 H) 7.57-7.69 (m, 1 H) 7.73-7.85 (m, 1 H) 7.89-7.99 (m, 1 H) 8.01 (dd, J=9.01, 2.76 Hz, 1 H) 8.48 (d, J=2.57 Hz, 1 H) 8.52-8.66 (m, 1 H) 8.83-8.98 (m, 1 H) 10.16 (s, 1 H) 10.20 (s, 1 H); MS (ESI+) m/z 538 (M+H)+, 560 (M+Na)+, (ESI−) m/z 536 (M−H)−.
