Following a procedure analogous to that for the synthesis of Intermediate 116B, (S)-1-(3-(hydroxymethyl)-3,4-dihydroisoquinolin-2(1H)-yl)ethanone (Intermediate 116A, 40.0 mg, 0.20 mmol) and ((2-bromoethoxy)methyl)benzene (92 μl, 0.58 mmol) were converted to the title compound (43 mg, 65%) after purification by flash column chromatography (gradient from 0% to 50% EtOAc/hexanes). 1H NMR (CDCl3, 2:1 mixture of amide rotamers) δ 7.41-7.25 (m, 5H), 7.24-7.06 (m, 4H), 5.10 (d, J=18.0 Hz, 1H), 4.66-4.44 (m, 3H), 4.39 (q, J=5.9 Hz, 0.5H), 4.26 (d, J=17.8 Hz, 0.5H), 3.68-3.47 (m, 5H), 3.44-3.27 (m, 1.5H), 3.10 (dd, J=5.8, 16.0 Hz, 0.5H), 3.01-2.80 (m, 1H), 2.24 (s, 2H), 2.19 (s, 1H); MS(ESI+) m/z 340.2 (M+H)+.
