To a solution of 7-amino-1-methyl-1,2,3,4-tetrahydroquinoline (D3) (31 mg, 0.19 mmol) in DCM (1 ml) was added 6-(4-fluorophenyl)-2-methylnicotinic acid (D24) (44 mg, 0.19 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (44 mg, 0.23 mmol) and 4-dimethylaminopyridine (11 mg, 0.09 mmol) and the reaction stirred at ambient temperature overnight. The crude reaction mixture was loaded directly onto a silica SPE column and eluted with 0-2% methanol/DCM to give the title compound as a solid. 1H NMR (400 MHz, CDCl3) δ (ppm): 8.02 (dd, 2H), 7.84 (d, 1H), 7.57 (d, 1H), 7.35 (br, 1H), 7.17 (t, 2H), 7.00 (s, 1H), 6.93 (d, 1H), 6.74 (d, 1H), 3.25 (m, 2H), 2.93 (s, 3H), 2.80 (s, 3H), 2.74 (m, 2H), 1.96 (m, 2H)
