Product 1

HCID 233304534-Methyl-6-{3-[4-(4-methylbenzyl)-piperazin-1-yl]-propoxy}-2-oxo-1,2-dihydroquinoline

Procedure

4-Methyl-6-hydroxy-2-oxo-1,2dihydroquinoline is reacted with 3-[4-(4-methylbenzyl)-piperazin-1-yl]-propyl chloride in a manner analogous to that described in Example 5. There is obtained 4-methyl-6-{3-[4-(4-methylbenzyl)-piperazin-1-yl]-propoxy}-2-oxo-1,2-dihydroquinoline which, after recrystallization from diethyl ether, melts at 162°-163° C.
