Procedure

To a stirred solution of 2.30 g (9.24 mmol) 7-fluoro-2-hydroxy-4-methylquinoline-3-carboxylic acid ethyl ester in DCM (60 ml) were added 6.36 g (23.1 mmol) Ag2CO3 and 1.44 ml (23.1 mmol) iodomethane at RT. The reaction mixture was stirred at RT for 16 h. Then the mixture was filtered through celite and the filtrate was concentrated in vacuum. After CC (EtOAc/hexane 1:4) of the residue, 1.50 g (5.70 mmol, 62%) 7-fluoro-2-methoxy-4-methylquinoline-3-carboxylic acid ethyl ester were obtained.
