온도

20 °C

Triethylamine (0.298 ml, 2.14 mmol) was added in one portion to 3-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid (1b) (200 mg, 0.71 mmol), 4-(cyclopentyloxy)piperidine hydrochloride (121 mg, 0.71 mmol) and O-benzotriazol-1-yl-N,N,N′,N′-tetra-methyluronium hexafluorophosphate (352 mg, 0.93 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 (120 mg, 39% yield); 1H NMR (400.132 MHz, DMSO) δ 1.22-1.86 (11H, m), 3.00-3.20 (2H, m), 3.25-3.43 (2H, m), 3.52-3.56 (1H, m), 3.91-4.05 (2H, m), 4.35 (2H, s), 7.20 (1H, d), 7.31 (1H, s), 7.34-7.40 (2H, m), 7.80-7.89 (2H, m), 7.96 (1H, d), 8.26 (1H, d), 12.57 (1H, s); m/z (LC-MS, ESI+), RT=2.18 (M+H 432.1)
