実験手順

A solution of (S)-1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (200 mg, 0.97 mmol), benzoic acid (122.5 mg, 1.07 mmol), HATU (387.6 mg, 1.02 mmol) and TEA (196.1 mg, 1.94 mmol) in DCM (20 mL) was stirred at room temperature for 2 h until completion of the reaction. The reaction mixture was then diluted with water and extracted with DCM (20 ml×2). The combined organic layers were dried and concentrated with the residue purified by pre-HPLC and SFC separation to give the desired compound (55 mg, Yield 18%). 1H NMR (400 MHz, MeOD): 7.66 (d, J=8.0 Hz, 2H), 7.36-7.34 (m, 1H), 7.26 (d, J=7.6 Hz, 2H), 6.99-6.89 (m, 4H), 4.01-3.96 (m, 1H), 3.61 (s, 2H), 3.43-3.37 (m, 2H), 2.77-2.72 (m, 4H), 2.56-2.53 (m, 2H). LCMS (m/z): 311.1 (M+1).
