Procedure

To a solution of 3-(1H-benzo[d]imidazol-2-yl)propanoic acid (300 mg, 1.579 mmol) in DCM (10 mL) was added HATU (722 mg, 1.895 mmol) and TEA (478 mg, 4.737 mmol). After stirring for 30 min at room temperature, (R)-1-amino-3-(3,4-dihydro isoquinolin-2(1H)-yl)propan-2-ol (488 mg, 2.368 mmol) was added and the resulting mixture then stirred at room temperature for 16 h. Once TLC analysis showed the reaction to be complete, the solvent was evaporated at reduced pressure and the residue purified by preparative HPLC to give the title compound (184.6 mg, 30.9%) as white solid. 1H NMR (400 MHz, METHANOL-d4) δ=7.56-7.46 (m, 2H), 7.22-7.17 (m, 2H), 7.13-7.07 (m, 3H), 7.02-6.97 (m, 1H), 3.94 (t, J=5.8 Hz, 1H), 3.61 (d, J=3.3 Hz, 2H), 3.40-3.35 (m, 1H), 3.25-3.18 (m, 3H), 2.89-2.84 (m, 2H), 2.79 (t, J=7.4 Hz, 2H), 2.74-2.69 (m, 2H), 2.47 (d, J=6.5 Hz, 2H). LCMS (m/z): 379.1 [M+H]+.
