Versuchsvorschrift
The solution of 12-7 (41 mg, 0.074 mmol) in TFA (0.5 mL) was stirred for 1 h at rt. The excess TFA was removed under reduced pressure. The residue was dissolved in dichloromethane (10 mL) and adjusted to pH=9-10 with saturated NaHCO3 aqueous solution. The mixture was extracted with EtOAc, dried over sodium sulfate, concentrated under reduced pressure and purified by reverse phase column (Waters Sunfire Prep C18 OBD, 5-95% methanol in water with 0.1% NH3H2O modifier). The product was obtained as a white solid (22 mg, 65%). 1H NMR (500 MHz, CDCl3) δ 8.36 (s, 1H), 7.51 (s, 1H), 7.12 (d, J=4.8 Hz, 1H), 5.63 (s, 1H), 5.43 (s, 1H), 4.91 (d, J=6.3 Hz, 2H), 4.36 (d, J=6.8 Hz, 2H), 3.66 (s, 1H), 2.73 (s, 3H), 2.47 (s, 3H), 2.33 (m, 4H), 2.03 (m, 1H), 1.06 (s, 9H); LRMS (ES) calculated M+H for C23H31N6O2S: 455.6.
