Procedure

A 16 mL vial was successively charged with (2E)-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylic acid hydrochloride (40 mg, 0.16 mmol), DMF (3.8 mL), 3-(pyrrolidin-3-yloxy)pyridine hydrochloride (64 mg, 0.32 mmol; which may be prepared as described in Step 2), DIPEA (63 μL, 0.38 mmol) and HATU (72 mg, 0.19 mmol). The reaction mixture was stirred at room temperature overnight and concentrated to dryness. The residue was purified on chromatography column (eluent: dichloromethane/MeOH, 95/5) to give a beige solid. This solid was triturated in acetone and diethyl ether, filtered, washed with acetone and diethyl ether then dried to give the title compound (7.3 mg, 13%) as a beige solid.
