実験手順

To a stirred solution of 45 (150 mg, 0.513 mmol) in DCM (5 mL) was added TFA (1 mL) at 0° C. and allowed to stir at rt for 2 h. The reaction mixture was concentrated, the residue was dissolved in MeOH and treated with Ambersep-900-OH resin to basify the solution, then filtered to separate the resin and concentrated the filtrate to obtain the desired amine (90 mg, 88%) as a gummy liquid. (m/z): 194 [MH]+; 1H NMR (400 MHz, DMSO-d6) δ 7.87 (1H, d, J=5.6 Hz), 6.57 (1H, d, J=2.4 Hz), 6.33 (1H, dd, J=5.2, 2.4 Hz), 5.90 (2H, br s), 3.58-3.56 (4H, m), 3.34 (2H, s), 2.38-2.36 (4H, m).
