実験手順

A6 (3.60 g, 5.81 mmol) was dissolved in TFA (29.0 mL). The mixture was stirred at 140° C. for 40 min in the microwave. After cooling to room temperature, the reaction mixture was concentrated under vacuum. The crude product was purified by Strong Cation Exchange (SCX) with MeOH as eluent, followed by rinsing with 0.7 N NH3 in MeOH to obtain the pure free base as yellow solid (2.22 g). 1H NMR (400 MHz, DMSO-D6, 300K): δ=1.64 (2H, d, J=12.8 Hz), 2.15 (2H, br dt, J=13.0 Hz), 2.71 (2H, t, J=11.9 Hz), 2.89 (2H, d, J=11.2 Hz), 3.46 (2H, s), 4.12 (1H, br s), 7.24 (1H, s), 7.35 (1H, t, J=7.4 Hz), 7.37 (1H, s), 7.46 (1H, t, J=7.4 Hz), 7.75 (1H, d, J=8.2 Hz), 7.81 (1H, d, J=5.6 Hz), 7.83 (1H, d, J=8.6 Hz), 8.09 (1H, s), 8.76 (1H, d, J=5.4 Hz), 11.78 (1H, br s); MS (ES) C23H21N5O2 requires: 399. found: 400.1 [M+H]+.
