Reaction Steps

A 4 mL vial with stirbar was charged with sodium hydride, dry 95% (2.9 mg, 0.115 mmol), placed in an ice bath and charged with a solution of Example 1H (0.0527 g, 0.097 mmol) in DMF (1 mL). After stirring 10 min at 0° C., iodomethane (8 μL, 0.128 mmol) was added by syringe. After 1 hour, the mixture was partitioned between 25 mL each of ethyl acetate and aqueous ammonium chloride. The organics were dried over anhydrous sodium sulfate. After filtration and solvent removal, the material was purified by reverse phase HPLC (C18, CH3CN/water (0.1% TFA), 0-100%) to afford the title compound. 1H NMR (400 MHz, DMSO-d6) δ 10.26 (s, 1H), 7.60 (d, J=2.6 Hz, 1H), 7.58 (s, 1H), 7.54-7.49 (m, 2H), 7.46-7.25 (m, 2H), 7.22-6.92 (m, 3H), 6.87 (d, J=8.8 Hz, 1H), 5.79 (s, 1H), 4.15 (q, J=7.1 Hz, 1H), 3.93 (d, J=7.0 Hz, 2H), 3.34 (s, 3H), 1.47 (d, J=7.1 Hz, 3H), 1.14 (t, J=6.9 Hz, 3H). MS (ESI) 557.1 (M+H)+.
