General Remarks: The chemicals procured from reputed suppliers were used in the present study and were either of analytic reagent (AR) or laboratory reagent (LR) grades. (TLC) using 0.25 mm silica gel plates monitored progress of each reaction in the present investigation by using silica gel as stationary phase and various combinations of solvents as mobile phase. Purity of the compounds was also checked by TLC. The melting points (MP) of purified organic product compounds were measured by taking solid compounds in capillary tubes using SUPERFIT India’s melting point measuring equipment and the MP values are uncorrected. Known compounds were first checked by comparing their melting point values to those of the available in literature. Apart from that IR and NMR techniques were employed for the spectral characterization of products synthesized. 1H NMR spectra were recorded at Varian’s Avance 400 MHz. The Infra Red (IR) spectra of the synthesized compounds were recorded on a Fourier Transform-Infra Red Spectrophotometer (Model Shimadzu 8700) using KBr pellets and values of Vmax are reported in cm−1.
