(1,1'-Biphenyl)-4-carboxylic acid → N-[1-(2-Methoxyethyl)-1,2,3,4-tetrahydroquinolin-7-yl]-1,1'-biphenyl-4-carboxamide

Participants

Reaction Steps

To a solution of 7-amino-1-(2-methoxyethyl)-1,2,3,4-tetrahydroquinoline (D13) (72 mg, 0.35 mmol) in DCM (2.5 ml) was added 4-biphenylcarboxylic acid (104 mg, 0.53 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (97 mg, 0.53 mmol) and 4-dimethylaminopyridine (6 mg, 0.05 mmol) and the reaction stirred at ambient temperature overnight. The mixture was diluted with DCM, washed with 2M sodium hydroxide solution, dried over MgSO4 and concentrated in vacuo to give the crude product which was purified by silica SPE chromatography. Elution with 20% EtOAc/60-80° C. petroleum ether gave the title compound as a pale yellow solid. 1H NMR (250 MHz, CDCl3) δ (ppm): 7.93 (d, 2H), 7.77 (br, 1H), 7.69 (d, 2H), 7.62 (d, 2H), 7.47 (t, 2H), 7.39 (t, 1H), 7.06 (d, 1H), 6.91 (d, 1H), 6.73 (dd, 1H), 3.63 (t, 2H), 3.49 (t, 2H), 3.37 (s, 3H), 3.36 (t, 2H), 2.73 (t, 2H), 1.91 (m, 2H).
