Procedure

1-[(4-Nitrophenyl)acetyl]piperidine was alkylated with methyl -bromoacetate in the same manner as in Reference Example 47, hydrolyzed with 1 M sodium hydroxide aqueous solution in methanol, and then condensed with 1-methylpiperazine in the same manner as in Reference Example 5 to obtain 1-methyl-4-[3-(4-nitrophenyl)-4-oxo-4-piperidin-1-ylbutanoyl]piperazine (ESI: 389). This piperazine compound was subjected to the reduction of nitro group in the same manner as the catalytic hydrogenation shown in Reference Example 3 and then treated with lithium aluminum hydride to obtain 4-[3-(4-methylpiperazin-1-yl)-1-(piperidin-1-ylmethyl)propyl]aniline. ESI: 331.
