Reaction Steps

To a solution of 4-((tetrahydro-2H-pyran-4-yl)oxy)benzoic acid (150 mg, 0.67 mmol) in DMF (4 mL) was added DIEA (260 mg, 2.01 mmol), HATU (384 mg, 1.01 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (170 mg, 0.81 mmol). The reaction mixture was stirred at 22° C. for 16 h. The mixture was treated with water and extracted with EA. The organic layer was washed with brine, dried over Na2SO4, concentrated and the residue was was purified by prep-HPLC to give the title compound (206.1 mg, Yield 74.9%). 1H NMR (CD3OD, 400 MHz): δ 7.84 (d, J=8.8 Hz, 2H), 7.26-7.37 (m, 3H), 7.19-7.25 (m, 1H), 7.05 (d, J=8.8 Hz, 2H), 4.59-4.74 (m, 2H), 4.31-4.49 (m, 2H), 3.93-4.01 (m, 2H), 3.86 (brs, 1H), 3.63 (ddd, J=11.7, 8.8, 3.0 Hz, 2H), 3.53 (qd, J=14.0, 5.7 Hz, 3H), 3.37-3.44 (m, 1H), 3.11-3.32 (m, 3H), 2.02-2.12 (m, 2H), 1.69-1.81 (m, 2H). LCMS (m/z): 411.2 (M+1).
