N1-(S-(4-methoxybenzyl)thiosalicyloyl)-N4-benzylpiperazine (compound 5) was prepared using the same procedure described above using: 10 mM(2.743 g) of S-(4-methoxybenzyl) thiosalicylic acid, 3 mM(728 mg) of 1-Benzylpiperazine and 20 mM (3.525 g) triethylamine. The product was dissolved in 5 ml of methylene chloride and purified by column chromatography on a silica gel column (eluent: Ethyl acetate) to give 870 mg (20.1%) of a white crystal. The product was then further purified by crystallization from hexane. The purified product had having a melting point of 84-85° C. and had the following specifications:
