Procedure

A solution of 3-(3-fluoro-4-(pyrrolo[2,1-f][1,2,4]triazin-4-yloxy)phenylamino)-3-oxopropanoic acid (17 mg, 0.052 mmol), BOP reagent (34 mg, 0.077 mmol), 4-methylmorpholine (28 μL, 0.26 mmol), and aniline (4.7 μL, 0.052 mmol) in dimethylformamide (0.5 mL) was stirred at room temperature for 16 h. The reaction was diluted with EtOAc (4 mL) and washed with water, 10% aq LiCl solution, and brine (1×3 mL each). The organic solution was dried over anhydrous Na2SO4 and then concentrated in vacuo. Purification by flash chromatography on silica gel (SiO2, EtOAc/Hexane 7:3) gave the desired compound as a white solid. The product was lyophilized with acetonitrile/water to give the title compound (12 mg, 57%) as a white powder. 1H NMR (CDCl3) δ 9.23 (br s, 1H), 8.22 (br s, 1H), 7.90 (s, 1H), 7.72 (m, 1H), 7.46 (d, 1H, J=8.2 Hz), 7.20 (m, 7H), 6.95 (m, 1H), 6.78 (m, 1H), 3.47 (s, 2H); MS(ESI+) m/z 406.1 (M+H)+.
