実験手順
A mixture of 6-bromo-7-methylquinolin (10 g, 42.0 mmol, prepared following J. Med. Chem. 1988, 31, 2048.), N-methyl-2-pyrrolidinone (32 mL), and CuCN (11 g, 0.13 mol) was stirred at 20° C. overnight and then at reflux temperature (202° C.) for 7 h. The mixture was poured into water (250 mL) and filtered, and the solid was washed twice with water to furnish 7-Methyl-2-oxo-1,2-dihydroquinoline-6-carbonitrile.
