Reaction Steps

Suspend 2-methoxy-4-[2-(4-methoxy-phenyl)-7-oxo-4,7-dihydro-5H-thieno[2,3-c]pyridin-6-yl]-benzoic acid (0.1451 g, 0.35 mmol) in DMF (5 mL) and add 2-pyrrolidin-1-yl-ethylamine (45 mg, 0.39 mmol), EDCI (81 mg, 0.42 mmol), HOBt (57 mg, 0.42 mmol) and Et3N (0.15 mL, 1.06 mmol). Stir the reaction at RT overnight. Dilute with EtOAc (100 mL), wash with water (2×30 mL), and dry over Na2SO4. Purify the crude material by silica gel chromatography, eluting with 2% NH3—H2O, 50% CH3OH/EtOAc to give 9 mg (5%) of the title compound. LC-MS/ES m/z 506.2 [M+H]+.
