Versuchsvorschrift

A mixture of 4-(4-fluorophenyl)-2-isopropyl-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazine-6-carboxylic acid (500 mg, 2 mmol), 4-(6,7-dimethoxyquinolin-4-yloxy)-3-fluorophenylamine (535 mg, 1.70 mmol), N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (639 mg, 1.68 mmol) and N,N-diisopropylethylamine (279 uL, 1.60 mmol) in N,N-dimethylformamide (8 mL) was stirred at rt for 3 h. The solvent was removed and the residue dissolved in EtOAc and washed with saturated NaHCO3 solution water and brine. After drying over magnesium sulfate, solvent was evaporated and the product was purified by ISCO silica gel chromatography (hexane: EtOAc 1:4) to give 835 mg (83%), which triturated with ether and dried. mp=225-226° C.; LCMS m/z=590 (M+1); 1H NMR DMSO) δ: 10.87 (s, 1H), 8.49 (d, 1H, J=5.2 Hz), 7.97 (dd, 1H, J=12.6, 2.2 Hz), 7.59-7.36 (m, 8H), 6.50 (d, 1H, J=4.9 Hz), 4.90 (m, 1H), 3.95 (s, 6H), 3.32 (s, 3H), 1.38 (d, 6H, J=6.6 Hz).
