Participants

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-hydroxy-4-phenylpiperidine (25 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. The residue was purified on preparative TLC (eluent: dichloromethane/MeOH, 95/5) to give a white solid. This solid was triturated in acetone and diethyl ether, filtered, washed with diethyl ether and then dried to give the title compound (18.5 mg, 41%) as a white solid.
