Procedure

A solution of 7-(4-amino-2-fluorophenoxy)-N′,N′-dimethylthieno[3,2-b]pyridine-2-carbohydrazide 239 (200 mg, 0.578 mmol), 3-(2-methoxyphenylamino)-3-oxopropanoic acid 27 (195 mg, 0.693 mmol), and EDC (230 mg, 0.693 mmol) in DMF (8.3 mL) was stirred overnight at room temperature. More 27 (195 mg, 0.693 mmol) and EDC (230 mg, 0.693 mmol) were added and the mixture stirred 6 h more. The crude was diluted with EtOAc, extracted with water, over with anhydrous Na2SO4, and concentrated under reduced pressure. The residue was re dissolved in MeOH and purified twice by flash chromatography (DCM/MeOH 9:1) affording 236 (207 mg, 0.385 mmol, 67% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.60 (s, 1H), 9.94 (s, 0.5H), 9.63 (s, 1H), 9.49 (s, 0.5H), 8.57 (dd, J=5.5 Hz, J=7.2 Hz, 1H), 8.26 (m, 1H), 8.07 (d, J=7.4 Hz, 1H), 7.88 (d, J=12.9 Hz, 1H), 7.54-7.43 (m, 2H), 7.07 (m, 2H), 6.91 (m, 1H), 6.73 (m, 1H), 3.86 (s, 3H), 3.65 (s, 2H), 2.63 (s, 3H), 2.61 (s, 3H). MS (m/z): (M+1) 538.0 (100%).
