The piperazine (IX) was alkylated with benzyl bromoacetate (X) to give ester (XI), which was converted to carboxylic acid (XII) by catalytic hydrogenolysis of the benzyl ester group. Then, coupling of (XII) with 1-amino-4-methylpiperazine (XIII) produced the corresponding hydrazide. Finally, treatment with fumaric acid in EtOH generated the title fumarate salt.
