[4-(3-Aminophenyl)-8-(trifluoromethyl)quinolin-3-yl](phenyl)methanone (0.39 g, 1.0 mmol) and (4-formyl-phenyl)-acetic acid methyl ester (0.17 g, 0.96 mmol) were mixed in THF (15 mL) and then treated with NaBH(OAc)3 (0.43 g, 2.0 mml) and acetic acid (0.5 mL). After stirring at 40° C. under a N2 atmosphere for 2 h the mixture was quenched with water and then extracted with ethyl acetate. The organic residue was purified by silica gel chromatography using 5-50% EtOAc/hexanes as eluent to provide methyl {4-[({3-[3-benzoyl-8-(trifluoromethyl)quinolin-4-yl]phenyl}amino)methyl]phenyl}acetate as an orange solid (0.30 g, 54%): MS (EI) m/z 555.3 (M+H)+; 1H NMR (DMSO-d6): δ 3.61 (s, 3H), 3.66 (s, 2H), 4.12 (d, J=6.0 Hz, 2H), 6.40 (d, J=6.8 Hz, 2H), 6.49 (d, J=6.8 Hz, 2H), 6.98 (t, J=7.7 Hz, 1H), 7.18-7.22 (m, 4H), 7.36 (t, J=7.5 Hz, 2H), 7.55 (t, J=7.4 Hz, 1H), 7.59 (d, J=9.0 Hz, 2H), 7.72 (t, J=8.6 Hz, 1H), 7.99 (d, J=8.5 Hz, 1H), 8.30 (d, J=7.3 Hz, 1H), 9.08 (s, 1H).
