Versuchsvorschrift

To a solution of ethanesulfonic acid [5-(7-fluoro-1-methyl-2-oxo-1,2,3,4-tetrahydro-quinolin-6-yl)-pyridin-3-ylmethyl]-amide (example 16, 0.15 g, 0.39 mmol) in DMF (5 mL) was added potassium tert-butoxide (67.2 mg, 0.60 mmol) at 0° C. The resulting mixture was stirred for 30 minutes at 0° C. before methyl iodide (84.6 mg, 0.6 mmol) was added dropwise. After stirring for 2 hours, the mixture was treated with water, and extracted with EtOAc. The combined organic layers were then washed with water and brine in sequence, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was then purified by flash chromatography (silica gel, 5% methanol in dichloromethane) to afford the title compound (93 mg, 60%) as a white solid. MS: 392.1 (M+H+)+.
