実験手順

A solution of 48 (1.456 g, 2.35 mmol) and TFA (15 mL) in DCM (50 mL) was stirred at RT for 5 hr. The TFA was removed by co-evaporation with DCM, the residue was diluted with water, and the pH was adjusted to ˜12-13 with 1N NaOH. The resultant suspension was sonicated for 15 min. The solid was collected by filtration, rinsed with water and dried under high vacuum to afford the title compound 49 (1.227 g, traces of TEA) as an off-white fluffy solid. 1H NMR (400 MHz. DMSO-d6) δ (ppm): 8.76 (bs, 1H), 8.54 (d, J=1.4 Hz, 1H), 8.52 (d, J=5.5 Hz, 1H), 8.32 (s, 1H), 8.24 (d, J=8.2 Hz, 1H), 7.85 (dd, J=8.1, 2.1 Hz, 1H), 7.73 (dd, J=13.5, 2.3 Hz, 1H), 7.38 (t, J=9.1 Hz, 1H), 7.20 (bd, J=10.2 Hz, 1H), 6.64 (d, J=5.5 Hz, 1H), 6.62 (bs, 1H), 3.58-3.48 (m, 2H), 2.73-2.64 (m, 4H), 2.59-2.52 (m, 1H), 2.38-2.25 (m, 4H), 0.69-0.62 (m, 2H), 0.46-0.40 (m, 2H), one NH is missing. MS (m/z): 519.6 (M+H).
