Reaction Steps

To a solution of 62 in DCM (190 mg, 0.24 mmol) was added TFA (excess) at room temperature and the reaction mixture was stirred for 3 hrs, evaporated under reduced pressure and the residual solid was triturated with Et2O to afford the title compound 63 as the di-TFA salt (100 mg, 51% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 12.49 (s, 1H), 11.84 (s, 1H), 8.89 (s, 1H), 8.53 (d, J=5.1 Hz, 1H), 8.14 (s, 1H), 8.01 (m, 1H), 7.62 (dd, J=2.5 and 7.7 Hz, 2H), 7.54 (d, J=2.7 Hz, 2H), 7.33 (m, 4H), 7.28 (m, 1H), 6.67 (d, J=5.5 Hz, 1H), 4.64 (m, 1H), 4.30 (m, 1H), 4.22 (t, J=5.3 Hz, 2H), 3.82 (s, 2H), 3.63 (t, J=5.3 Hz, 2H), 2.98 (m, 1H).
