실험 절차

Under an atmosphere of argon, a 1M solution of lithium hexamethyldisilazane in THF (0.27 ml) was added dropwise to a stirred solution of N-(3-pyridyl)-2-[4-(6-cyano-7-methoxyquinolin-4-yloxy)phenyl]acetamide (0.1 g) in DMF (2 ml) that had been cooled to −5° C. After 5 minutes, a solution of dimethyl sulphate (0.026 ml) in DMF (0.5 ml) was added dropwise and the resultant mixture was stirred at 0° C. for 30 minutes. The mixture was evaporated and the residue was purified by preparative HPLC using a Waters ‘Xterra’ reversed-phase column (5 microns silica) using decreasingly polar mixtures of water (containing 0.2% ammonium carbonate) and acetonitrile as eluent. There was thus obtained the title compound (0.04 g); 1H NMR: (CDCl3) 3.34 (s, 3H), 3.52 (s, 2H), 4.08 (s, 3H), 6.51 (d, 1H), 7.07 (d, 2H), 7.18 (d, 2H), 7.42 (m, 1H), 7.53 (br s, 2H), 8.5 (br s, 1H), 8.65 (br s, 1), 8.67 (d, 1H), 8.69 (s, 1H); Mass Spectrum: M+H+ 425.
