실험 절차

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), 3-phenoxyazetidine hydrochloride (26 mg, 0.14 mmol; which may be prepared as described in Step 3), 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/NH3 7N in MeOH, 2.5%) to give a pale yellow solid. This solid was triturated in acetone, filtered, washed with acetone and diethyl ether then dried to give the title compound (15 mg, 36%) as a white solid.
