온도

20 °C

Triethylamine (0.280 ml, 2.01 mmol) was added in one portion to 2-fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid (1) (200 mg, 0.67 mmol), 4-(cyclopentyloxy)piperidine hydrochloride (113 mg, 0.67 mmol) and O-benzotriazol-1-yl-N,N,N′,N′-tetra-methyluronium hexafluorophosphate (331 mg, 0.87 mmol) in DMA (2 ml) at 20° C. under air. The resulting mixture was stirred at 20° C. for 3 days. The crude product was purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5μ silica, 19 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford the desired material as a white solid (112 mg, 37.2% yield); 1H NMR (400.132 MHz, DMSO) δ 1.23-1.72 (11H, m), 1.81-1.87 (1H, m), 3.00-3.06 (1H, m), 3.22-3.27 (2H, m), 3.52-3.59 (1H, m), 3.96-4.04 (2H, m), 4.33 (2H, s), 7.18-7.23 (1H, m), 7.34 (1H, d), 7.38-7.42 (1H, m), 7.81-7.91 (2H, m), 7.97 (1H, d), 8.26 (1H, d), 12.56 (1H, s); m/z (LC-MS, ESI+), RT=2.30 (M+H 450.1).
