1-Benzyl-azetidine-3,3-dicarboxylic acid was prepared by following the literature procedure (Miller, R. A.; et al. Syn. Comm. 2003, 33, 3347). To a solution of 4-(6,7-dimethoxy-quinolin-4-yloxy)-phenylamine (4.2 mmol, 1 equiv.) and 4-fluoroaniline (4.2 mmol, 1 equiv.) in DMF (20 mL) was charged with DIEA (12.6 mmol, 3 equiv) and a solution of 1-benzyl-azetidine-3,3-dicarboxylic acid (4.2 mmol, 1 equiv.) in DMF (10 mL). The reaction mixture was allowed to stir at RT and monitored by LCMS. The reaction was complete in 6 h. The reaction mixture was diluted with ethyl acetate and washed with 10% LiCl (3×), brine (3×), dried with sodium sulfate, filtered and the solvent was reduced in vacuo. The crude product was purified by silica gel chromatography eluting with 2% of MeOH in EtOAc. The fractions containing the desired product were further purified using preparative HPLC to give ′N-(4-{[6,7-bis(methyloxy)quinolin-4-yl]oxy}phenyl)-N′-(4-fluorophenyl)-1-(phenylmethyl)azetidine-3,3-dicarboxamide (300 mg, 12% yield) as a white solid. 1HNMR (DMSO-d6): 10.0 (s, 1H), 9.90 (s, 1H), 8.45 (d, 1H), 7.80 (d, 2H), 7.70 (m, 2H), 7.50 (s, 1H), 7.40 (s, 1H), 7.48-7.15 (m, 9H), 3.95 (s, 6H), 3.70 (s, 4H), 3.60 (s, 2H). LCMS (POS): 607.2 (M+H).
