In a manner analogous to that described in Example 1, 3-n-butyl-4-methyl-7-hydroxy-2-oxo-1,2-dihydroquinoline is reacted with 3-[4-(4-chlorobenzyl)-piperazin-1-yl]-propyl chloride in ethoxyethanol. There is obtained 3-n-butyl-4-methyl-7-{3-[4-(4-chlorobenzyl)-piperazin-1-yl]-propoxy}-2-oxo-1,2-dihydroquinoline in a yield of 57.5% of theory; m.p. 148°-149° C.
