Reaction Steps

A mixture of compound 2-(4-methoxyphenoxy)acetic acid (100 mg, 0.51 mmol), 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (132 mg, 0.51 mmol), BOP-Cl (156 mg, 0.61 mmol) and DIPEA (1 mL) in DCM (10 mL) was stirred at room temperature for 4 h. The solvent was removed by concentration and the crude product was purified by pre-HPLC to give the title compound (7.8 mg, yield: 3.8%). 1H NMR (500 MHz, MeOD): δ 7.45 (d, d, J=8.8 Hz, 2H), 7.11-7.05 (m, 3H), 7.02-7.00 (m, 1H), 6.88 (d, J=8.8 Hz, 2H), 4.50 (s, 2H), 4.01-3.98 (m, 1H), 3.66 (d, J=3.2 Hz, 2H), 3.41 (dd, J=0.8, 6.0 Hz, 2H), 2.89-2.87 (m, 2H), 2.80-2.76 (m, 2H), 2.55 (d, J=6.0 Hz, 2H), 2.08 (s, 3H) ppm; ESI-MS (m/z): 398.2 [M+1]+.
