To a solution of (R)-methyl 2-(quinolin-8-yloxy)propanoate (100 mg, 0.433 mmol) in EtOH (1 mL) was added (R)-1-amino-3-(isoindolin-2-yl)propan-2-ol (83 mg, 0.433 mmol). The reaction mixture was heated under microwave conditions at 120° C. for 0.5 h, concentrated, and purified by preparative TLC first and then by preparative HPLC purification. (19 mg, yield 11%) MS (ESI+) e/z: 392.1 [M+1]+. 1H NMR (MeOD, 400 MHz), δ ppm: 8.90 (d, J=2.76 Hz, 1H), 8.34 (d, J=8.28 Hz, 1H), 7.64-7.48 (m, 3H), 7.34-7.24 (m, 1H), 7.23-7.08 (m, 4H), 5.07 (q, J=6.53 Hz, 1H), 3.97-3.71 (m, 5H), 3.49 (dd, J=13.55, 5.27 Hz, 1H), 3.29 (d, J=6.27 Hz, 1H), 2.71 (d, J=6.02 Hz, 2H), 1.72 (d, J=6.53 Hz, 3H).
