To a stirred mixture of 1-methyl-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine (30 mg, 0.219 mmol) in dioxane:H2O (6 mL, 2:1) was added 1-(3-bromophenoxy)-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (119 mg, 0.328 mmol), Cs2CO3 (213 mg, 0.657 mmol) and then Ruphos (2 mg) and Pd(Ruphos) (5 mg). The mixture was degassed by N2 4 times and stirred at 100° C. for 16 hours. The reaction mixture was then quenched with water (20 mL), extracted with ethyl acetate (3×20 mL). The combined extracts were washed with brine (20 mL), dried over anhydrous Na2SO4 and concentrated to yield a residue which was purified by prep-HPLC to afford 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(1-methyl-4,5-dihydro-1H-pyrazolo[3,4-c]pyridin-6(7H)-yl)phenoxy)propan-2-ol (17 mg, Yield 18.6%). 1H NMR (400 MHz, MeOD) δ=7.32 (s, 1H), 7.19-7.08 (m, 4H), 7.04 (d, J=5.8 Hz, 1H), 6.70-6.61 (m, 2H), 6.50-6.43 (m, 1H), 4.29-4.22 (m, 1H), 4.20 (s, 2H), 4.09-4.01 (m, 1H), 4.01-3.92 (m, 1H), 3.76 (s, 2H), 3.73 (s, 3H), 3.61 (t, J=5.8 Hz, 2H), 2.98-2.84 (m, 4H), 2.82-2.67 (m, 4H).
