Triethylamine → N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)-3-(pyridin-4-yl)benzamide

To a solution of 3-(pyridin-4-yl)benzoic acid (300 mg, 1.5 mmol) in DCM (6 mL) was added EDCI (430 mg, 2.20 mmol), HOBt (296 mg, 2.20 mmol), Et3N (556 mg, 4.50 mmol) and 1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (370 mg, 1.80 mmol). The mixture was stirred at room temperature for 16 h, then the reaction mixture was washed with water and extracted with DCM. The organic layer was then dried, concentrated and the residue purified by prep-HPLC to give the title product (230 mg, Yield 40%). 1H NMR (400 MHz, MeOD) δ 8.54 (d, J=4.0 Hz, 2H), 8.16 (s, 1H), 7.85-7.80 (m, 2H), 7.64 (dd J=4.0 Hz, 2H), 7.48 (dd, J=7.6 Hz, 1H), 7.03-6.95 (m, 4H), 4.13 (br.s, 1H), 3.66 (s, 2H), 3.60-3.48 (m, 2H), 2.80-2.77 (m, 4H), 2.63-2.59 (m, 2H). LCMS (m/z): 388.2 (M+1).
