Procedure
To a solution of 3-(1-methyl-1H-pyrazol-5-yl)benzoic acid (130 mg, 0.64 mmol) in DCM (6 mL) was added EDCI (245 mg, 1.28 mmol), HOBt (173 mg, 1.28 mmol), Et3N (195 mg, 1.93 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (132 mg, 0.64 mmol). The mixture was stirred at room temperature for 16 h until completion of the reaction was indicated by which TLC. The reaction solution was then diluted with water (10 mL) and extracted with DCM (2×10 mL) then the combined organic layers were concentrated. The residue was purified by prep-HPLC to give the desired product (60 mg, Yield 25%). 1H NMR (400 MHz, MeOD): 7.55 (s, 1H), 7.52 (s, 1H), 7.24-7.15 (m, 3H), 6.85-6.73 (m, 4H), 6.03 (s, 1H), 4.22 (br.s, 1H), 4.03-3.99 (m, 1H), 3.45 (s, 3H), 3.17-2.73 (m, 7H). LCMS (m/z): 391.2 (M+1).
