Reaction Steps

A mixture of Example 139 (0.05 g, 0.138 mmol) and sodium tetrahydroborate (2) (5.21 mg, 0.138 mmol) in tetrahydrofuran (2 mL) was heated at 60° C. for 3 hours. The solvent was removed, and the residue was purified by reverse phase Preparative HPLC (10-80% acetonitrile in 0.1% TFA/water) to give the title compound (0.042 g, 0.115 mmol, 84% yield). 1H NMR (500 MHz, DMSO-d6) δ ppm 11.70 (s, 1H), 7.56 (d, J=7.63 Hz, 1H), 7.35-7.39 (m, 1H), 7.27-7.31 (m, 1H), 7.21-7.23 (m, 4H), 7.00 (d, J=8.54 Hz, 2H), 6.79 (s, 1H), 5.94 (t, J=2.29 Hz, 1H), 5.75 (s, 1H), 3.47 (s, 3H). MS (DCI+) m/z 365.0 (M+H)+.
