To a solution of 2-(3-(1-methyl-1H-pyrazol-5-yl)phenyl)acetic acid (150 mg, 0.69 mmol) in DCM (6 mL) was added EDCI (265 mg, 1.38 mmol), HOBt (186 mg, 1.38 mmol), Et3N (209 mg, 2.07 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (142 mg, 0.69 mmol). The mixture was stirred at room temperature for 16 h then diluted with water (10 mL) and extracted with DCM (10 mL×3). The combined organic layers were concentrated. The residue was purified by prep-HPLC to give the product as a colorless oil (60 mg, Yield 21%). 1H NMR (400 MHz, MeOD): 7.47 (s, 1H), 7.43-7.33 (m, 4H), 7.08-7.04 (m, 3H), 6.96-6.94 (m, 1H), 6.35 (s, 1H), 3.96-3.91 (m, 1H), 3.83 (s, 3H), 3.60-3.59 (m, 4H), 3.38-3.20 (m, 2H), 2.84 (t, J=6.0 Hz, 2H), 2.72 (t, J=6.0 Hz, 2H), 2.49 (d, J=6.4 Hz, 2H). LCMS (m/z): 405.2 (M+1).
