To a stirred mixture of (R)-methyl 2-(quinolin-8-yloxy)propanoate (100 mg, 0.433 mmol) in EtOH (1 mL) was added (R)-1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl) propan-2-ol (89.2 mg, 0.433 mmol). The mixture was stirred in a sealed tube in a microwave apparatus at 120° C. for 0.5 hour. After cooling to room temperature the solvent was evaporated, and the residue was first purified by prep-TLC and then prep-HPLC to afford the title compound (90 mg, yield: 51%). 1H NMR (400 MHz, METHANOL-d4) δ ppm 8.89 (br.
