Procedure

A solution of (Z)-4-(2-(4-(dimethylamino)but-1-enyl)thieno[3,2-b]pyridin-7-yloxy)-3-fluoroaniline (235) (69.1 mg, 0.193 mmol), 3-(methyl(phenyl)amino)-3-oxopropanoic acid 31 (46 mg, 0.26 mmol) (scheme 10), and EDC (45 mg, 0.24 mmol) in DMF (2.8 mL) was stirred overnight at room temperature. More 31 (45 mg, 0.26 mmol) and EDC (45 mg, 0.24 mmol) were added and the mixture stirred 6 h more. The mixture was diluted with EtOAc, washed with water, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The residue was redissolved in MeOH and purified twice by preparative HPLC (gradient 40% to 95% MeOH in water, 45 min) giving title compound 231 (35 mg, 0.066 mmol, 34% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.32 (s, 1H), 8.48 (d, J=5.5 Hz, 1H), 7.80 (d, J=12.7 Hz, 1H), 7.54 (s, 1H), 7.5-7.3 (m, 7H), 6.78 (d, J=12.2 Hz, 1H), 6.62 (d, J=5.5 Hz, 1H), 5.92 (tt, J=7.2 Hz, J=4.5 Hz, 11.7 Hz, 1H), 3.21 (s, 5H), 2.59 (m, 2H), 2.42 (dd, 6.8 Hz, 7.4 Hz, 2H), 2.16 (s, 6H). MS (m/z): (M+1) 533.1 (100 N.
