Procedure

To a solution of EXAMPLE 1B (89 mg, 0.20 mmol) in 1,2-dimethoxyethane (2 mL) at 0° C. was added dropwise 3M phenylmagnesium bromide in diethyl ether (0.133 mL, 0.40 mmol)). The mixture was slowly warmed to room temperature and stirred for 15 minutes. To the solution was added dropwise 1M aqueous sodium hydroxide (2 mL, 2 mmol). The mixture was stirred at room temperature for 1 day and concentrated. The residue was dissolved in 12% aqueous HCl (0.62 mL, 2.25 mmol) and heated at 90° C. for 4 hours. The mixture was concentrated and purified by reverse phase HPLC to provide the title compound. MS (ESI) m/e 289 (M+H)+; 1H NMR (DMSO-d6) δ 6.78 (s, 1H), 7.25 (dd, J=7.93, 4.58 Hz, 1H), 7.54-7.65 (m, 3H), 8.24-8.34 (m, 3H), 8.44 (s, 1H), 8.69-8.75 (m, 1H), 12.32 (s, 1H).
