Piperazine is an organic compound consisting of a six-membered ring containing two nitrogen atoms in opposite positions in the ring. The chemical formula of piperazine is C4H10N2, and it is an important pharmaceutical intermediate. Pyrimidines and piperazines are known to be the backbone of many bulk compounds and important core structures for approved drugs; studies have shown that combining a pyridine ring with a piperazine moiety within a single structural framework enhances biological activity.
Benzotriazole is a bicyclic nitrogen heterocycle formed by the fusion of the benzene ring with the 4,5-positions or the “d” site of 1H-1,2,3-triazole. The benzotriazoles are known as important intermediates in the preparation of organic products such as β-amido ketones, aldehydes, β-ketoesters, ionic liquid, and as reagents for acylation and thioacylation reactions. 1H-Benzotriazoles are also known to exhibit broad spectrum of pharmacological activities. There are numerous benzotriazole-based clinically used drugs in the market for the treatment of various diseases.
