Ramesh et al. Keywords Glycerol Catalyst-free Bis(3-methyl-1H-pyrazol-5-ol) 2,3-Dihydroquinazolin-4(1H)-one Green synthesis Introduction The exploration of proﬁcient and environmentally benevolent routes for the preparation of medicinally privileged organic molecules is a central goal of synthesis research. Generally, nitrogen containing heterocycles are omnipresent in several natural and biologically active synthetic molecules [1–3], and they have emerged as core components in drug development because N-rich heterocyclic compounds often improve dissolution and can facilitate salt formation . Among the variety of nitrogen heterocyclics, pyrazole and quinazolinone compounds have received considerable interest, as they are present in natural as well as synthetic pharmacologically potent molecules [5–7]. Considering the many properties of glycerol, such as a long liquid range, unique solubility for polar organic compounds, non-ﬂammability and direct usage as a solvent, it would ﬁt perfectly the requirements of a green solvent . Due to their unique behaviours,
