Reaction Steps

A 16 mL vial flask was successively charged with (2E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid hydrochloride (30 mg, 0.12 mmol), DMF (3 mL), 4-N-propylpiperidine (18 mg, 0.14 mmol), DIPEA (48 μL, 0.28 mmol) and EDAC (27 mg, 0.14 mmol). The reaction mixture was stirred at room temperature overnight and concentrated to dryness. LC/MS showed the presence of the target compound and no starting material after 24 h. The residue was purified on preparative TLC (eluent: dichloromethane/NH3 7N in MeOH, 2.5%) to give a white solid. This solid was triturated in acetone, filtered, washed with acetone and diethyl ether to give the title compound (15 mg, 38%) as a white solid.
