Procedure

Under ice-cooling, 1-chloroethyl chloroformate was added to a 1,2-dichloroethane solution of 2-[(1-benzylpiperidin-4-yl)amino]-4-chloro-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)benzamide. This was stirred for 1 hour under heat reflux and then concentrated under a reduced pressure. After dissolving in methanol, this was stirred for 2 hours under heat reflux. After concentration of the reaction liquid under a reduced pressure, the residue was purified by silica gel column chromatography to obtain 4-chloro-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)-2-(piperidin-4-ylamino)benzamide.
