1,2-Dichloroethane → 6-Oxo-n-(2-piperidinoethyl)-3-(phenylamino)-7-phenyl-6,7-dihydrothieno[2,3-b]pyridine-2-carboxamide

To a suspension of the compound of Example 14 (90 mg, 0.23 mmol) in DCM (2 mL) was added EDC (60 mg, 0.30 mmol) and HOBT (41 mg, 0.30 mmol) and the mixture stirred at r.t. for 15 minutes. A solution 1-(2-aminoethyl)piperidine (45 mg, 0.35 mmol) in DCM (0.5 mL) was added and the reaction stirred at r.t. for 18 h. The reaction mixture was diluted with DCM (10 mL), washed with water (2×5 mL), dried (MgSO4) and concentrated in vacuo. The crude product was purified by chromatography on silica (0-20% THF in DCM) to give the title compound as an off-white solid (23 mg). δH (CDCl3) 8.61 (1H, s), 7.61-7.43 (3H, m), 7.40-7.27 (2H, m), 7.25-7.13 (3H, m), 7.00-6.89 (3H, m), 6.50 (1H, bs), 6.33 (1H, d, J 9.7 Hz), 3.43-3.25 (2H, m), 2.47-2.32 (2H, m), 2.31-2.11 (4H, m), 1.50-1.40 (4H, m), 1.39-1.25 (2H, m).
