实验步骤: The title product was prepared following the procedure of Example 64 (step a and b) but starting from (2R)-2-[(4S)-2,2-dimethyl-5-oxo-1,3-dioxolan-4-yl]-5-(4-methoxyphenyl)pentanoic acid (prepared following the procedure of Intermediate 2 but using 4-bromoanisole in step b) and 4-propylpiperidine (Aldrich). Purification by reverse-phase chromatography gave the title product as a yellow powder. M−(ESI): 405.4; M+(ESI): 407.4. HPLC (Condition A): Rt: 3.6 min (HPLC purity: 94.9%). The title product was prepared prepared Purification by reverse-phase chromatography

实验步骤: 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. concentrated to dryness 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
