To a solution of 2-((1-methyl-1H-benzo[d]imidazol-5-yl)oxy)acetic acid (160 mg, 0.776 mmol) in DMF (4 ml) was added TEA (336 mg, 3.33 mmol), HOBt (157 mg, 1.164 mmol), EDCI (223 mg, 1.164 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (192 mg, 0.931 mmol) at 29° C. The reaction mixture was stirred for 16 h at 29° C. until TLC showed the reaction to be complete. After evaporation of the solvent, the mixture was purified by preparative HPLC to give the title compound (13.1 mg, 4.2%) as colorless oil. 1H NMR (400 MHz, MeOD) δ 8.05 (s, 1H), 7.45 (d, J=8.8 Hz, 1H), 7.21 (d, J=2.0 Hz, 1H), 7.09-6.97 (m, 5H), 4.59 (s, 2H), 4.03-3.97 (m, 1H), 3.84 (s, 3H), 3.65 (dd, J1=14.8 Hz, J2=30.4 Hz, 2H), 3.47-3.42 (m, 2H), 2.88 (t, J=5.6 Hz, 2H), 2.72 (t, J=5.6 Hz, 2H), 2.53-2.51 (m, 2H). LCMS (m/z): 395.2 (M+1).
