Reaction Steps

To a stirred mixture of ethyl 2-(quinolin-8-yloxy)acetate (250 mg, 1.08 mmol) in EtOH (2 mL) was added (R)-1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (222 mg, 1.08 mmol). The mixture was stirred at 120° C. for 0.5 hour under microwave heating. After evaporation of the solvent, the residue was purified first by prep-TLC and then by prep-SFC to afford (160 mg Yield 40%). 1H NMR (400 MHz, MeOD) δ=8.791 (d, J=4.3 Hz, 1H), 8.30 (d, J=8.3 Hz, 1H), 7.51-7.46 (m, 3H), 7.17 (d, J=7.3 Hz, 1H), 6.94-6.85 (m, 4H), 4.65 (s, 2H), 4.00-3.99 (m, 1H), 3.59 (s, 2H), 3.44-3.32 (m, 2H), 2.77-2.71 (m, 4H), 2.53-2.51 (m, 2H). LCMS (m/z): 392.1 (M+1).
