Procedure

To a solution of 354 (230 mg, 0.325 mmol) in DCM (3 mL) was added TFA (0.5 mL). The reaction mixture was stirred at room temperature overnight then concentrated. The residue was partitioned between EtOAc and NaHCO3 saturated solution. The organic layer was collected, dried and concentrated. The residue was purified via Biotage (0-50% MeOH/EA; 10 g SNAP column) to afford a reddish solid which was purified again by flash column chromatography (eluent MeOH/EA, 20-25%) to give a yellowish solid which was triturated with ether to afford the title compound 355 (80 mg, 0.132 mmol, 40.5% yield) as an off-white solid. HNMR (dmso) d(ppm) 1H: 10.53 (s, 1H), 10.01 (s, 1H), 8.47 (d, 1H, J=5.5 Hz), 7.95 (m, 1H), 7.85-7.81 (m, 2H), 7.46 (t, 1H, J=8.8 Hz), 7.39 (d, 1H, J=10.9 Hz), 7.15-7.09 (m, 2H), 6.91 (s, 1H), 6.65 (d, 1H, J=5.5 Hz), 3.81 (s, 3H), 3.72 (s, 2H), 3.58 (s, 2H), 3.35 (t, 2H, J=5.6 Hz), 3.20 (s, 3H), 2.64 (t, 2H, J=5.6 Hz). MS: 607.2 (MH)+.
