Procedure

To a stirred mixture of ethyl 2-(naphthalen-1-yloxy)acetate (150 mg, 0.641 mmol) in EtOH (2 mL) was added 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (132 mg, 0.641 mmol). The mixture was stirred at 120° C. for 30 minutes under microwave mediated heating. After evaporation of the solvent, the reaction mixture was purified by prep-HPLC to afford the desired product (64 mg, Yield 25%). 1H NMR (400 MHz, METHANOL-d4) δ=8.41-8.31 (m, 1H), 7.90-7.80 (m, 1H), 7.58-7.46 (m, 3H), 7.44-7.35 (m, 1H), 7.18-6.95 (m, 5H), 6.91 (d, J=7.8 Hz, 1H), 4.76 (s, 2H), 4.05 (quin, J=6.0 Hz, 1H), 3.72-3.59 (m, 2H), 3.56-3.48 (m, 1H), 3.41 (dd, J=6.5, 13.6 Hz, 1H), 2.93-2.83 (m, 2H), 2.80-2.72 (m, 2H), 2.59-2.52 (m, 2H). LCMS (m/z): 391.2 (M+1).
