実験手順

To a solution of 2-(4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetic acid (70 mg, 0.232 mmol), 2-oxo-1-phenyl-1,2,5,6,7,8-hexahydro-1,6-naphthyridine-3-carbonitrile (58.4 mg, 0.232 mmol) and 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (90 mg, 0.279 mmol) in DMF (2 mL) was added N,N-diisopropylethylamine (0.406 mL, 2.324 mmol). The mixture was stirred at room temperature for 4 hours, and diluted with EtOAc (100 mL) and washed with 5% of NaHCO3 (20 mL), and brine (20 mL). The organic layer was dried over MgSO4 and concentrated under vacuum. The residue was purified by prep. HPLC and silica gel column (using EtOAc) to give 6-(2-(4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetyl)-2-oxo-1-phenyl-1,2,5,6,7,8-hexahydro-1,6-naphthyridine-3-carbonitrile (6.1 mg, 10.27 μmol, 4.42% yield). LCMS: m/z 535.09 (M+H)+, 1.65 min (method 7). 1H NMR (500 MHz, chloroform-d) δ ppm 11.07 (s, 1H) 9.05-9.12 (m, 1H) 8.18-8.27 (m, 1H) 7.45-7.78 (m, 5H) 7.14-7.21 (m, 2H) 4.50-4.73 (m, 2H) 3.95-4.04 (m, 3H) 3.64-3.90 (m, 2H) 2.53-2.57 (m, 3H) 2.42-2.50 (m, 2H).
