反応手順

To a solution of 7-amino-1-trifluoroacetyl-1,2,3,4-tetrahydroquinoline (D5) (122 mg, 0.5 mmol) in DCM (2 ml) was added 6-phenylnicotinic acid (D48) (119 mg, 0.6 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (111 mg, 0.6 mmol) and 4-dimethylaminopyridine (7 mg, 0.06 mmol) and the reaction stirred at ambient temperature for until complete by tlc. The mixture was then washed with 2M sodium hydroxide solution (1 ml), dried over magnesium sufate 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 an off-white solid which was recrystallised from EtOAc/60-80° C. petroleum ether giving the title compound as a white solid. 1H NMR (250 MHz, CDCl3) δ (ppm): 9.10 (d, 1H), 8.20 (m, 2H), 8.04 (m, 2H), 7.86 (br, 1H), 7.82 (dd, 1H), 7.72 (br, 1H), 7.50 (m, 3H), 7.19 (1H, d), 3.84 (m, 2H), 2.84 (m, 2H), 2.06 (m, 2H).
