Versuchsvorschrift

Acetyl chloride (0.37 g, 4.7 mmol) was added dropwise gradually under ice-cooling to a solution of 2-(2-chloro-6-methoxyquinolin-4-yl)ethylamine (1.0 g, 4.2 mmol) and triethylamine (0.87 g, 8.6 mmol) in tetrahydrofuran (50 ml). The reaction mixture was stirred at room temperature for 1 hour and poured into water. The organic materials were extracted with a mixed solvent of 5% methanol/ethyl acetate. The extract was washed with saturated brine and water and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The resulting residue was recrystallized from ethyl acetate to obtain the title compound (0.96 g, 80%).
