Procedure

A mixture of ethyl 2-((2-(methylsulfonyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)oxy)acetate (140 mg, 0.447 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (184 mg, 0.89 mmol) in EtOH (0.2 mL) was stirred at 120° C. for 30 min under microwave conditions. The mixture was diluted with MeOH and purified by prep-HPLC to afford N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)-2-((2-(methylsulfonyl)-1,2,3,4-tetrahydroisoquinolin-5-yl)oxy)acetamide (53.5 mg, 25%). 1H NMR (400 MHz, MeOD) δ 0.84 (s, 1H), 7.29-7.15 (m, 5H), 6.80 (d, J=8.2 Hz, 1H), 6.83 (d, J=7.7 Hz, 1H), 4.61 (s, 2H), 4.41 (s, 2H), 4.35-4.17 (m, 3H), 3.54 (t, J=6.1 Hz, 2H), 3.48-3.38 (m, 4H), 3.17-3.04 (m, 4H), 2.98 (t, J=6.0 Hz, 2H), 2.92 (s, 3H). LCMS (m/z): 474.2 [M+H]+.
