실험 절차

2-(1H-Benzo[d][1,2,3]triazol-1-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.163 g, 0.43 mmol) was added to 3-((5,7-dimethyl-1-oxo-2,6-dihydro-1H-pyrrolo[3,4-d]pyridazin-4-yl)methyl)benzoic acid (51) (0.091 g, 0.31 mmol), 4-ethoxypiperidine (0.044 g, 0.34 mmol) and triethylamine (0.107 mL, 0.77 mmol) in DMF (2 mL). The resulting solution was stirred at room temperature for 16 hours. 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 (0.028 g, 22.5% yield). 1H NMR (400.132 MHz, DMSO) δ 1.11 (3H, t), 1.16-1.95 (4H, m), 2.24 (3H, s), 2.51 (3H, s), 2.99-3.26 (2H, m), 3.33-3.54 (4H, m), 3.85-4.01 (1H, m), 4.09 (2H, s), 7.14 (1H, s), 7.20 (1H, d), 7.27 (1H, d), 7.35 (1H, t), 11.08 (1H, s), 11.92 (1H, s); m/z (LC-MS, ESI+), RT=1.53 min (M+H=409.13).
