実験手順

2-(1H-Benzo[d][1,2,3]triazol-1-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.179 g, 0.47 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) (0.100 g, 0.34 mmol), 4-methoxypiperidine (0.043 g, 0.37 mmol) and triethylamine (0.117 mL, 0.84 mmol) in DMF (2 mL). The resulting solution was stirred at room temperature for 5 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 compound (0.054 g, 40.9% yield). 1H NMR (400.132 MHz, DMSO) δ 1.18-1.93 (4H, m), 2.24 (3H, s), 2.51 (3H, s), 3.02-3.19 (2H, m), 3.25 (3H, s), 3.40 (2H, m), 3.76-3.97 (1H, m), 4.09 (2H, s), 7.14 (1H, s), 7.20 (1H, d), 7.27 (1H, d), 7.36 (1H, t), 11.08 (1H, s), 11.92 (1H, s); m/z (LC-MS, ESI+), RT=1.38 min (M+H=395.09).
