Procedure

Title compound 350 (147 mg, 0.43 mmol), hydroxylamine (50% in water, 6 mL) and sodium hydroxide (138 mg, 3.40 mmol) were stirred in methanol (3 mL) and THF (3 mL) at room temperature overnight. The organic solvent was evaporated and the precipitate was filtered off and washed with a little bit of cold methanol to afford title compound 351 (39 mg, 26%) as a yellow solid. 1H NMR (DMSO-d6) δ (ppm): 11.06 (s, 1H), 8.96 (s, 1H), 7.57 (d, J=8.4 Hz, 2H), 7.47 (d, J=8.4 Hz, 2H), 7.21 (td, J=1.6 and 7.2 Hz, 2H), 7.18-7.13 (m, 2H), 7.10 (dd, J=1.6 and 7.6 Hz, 2H), 6.6 (td, J=1.2 and 7.2 Hz, 2H), 6.85 (s, 2H), 5.00 (s, 2H). LRMS: 342.1 (calc). 343.2 (found).
