The structural assignments were made by NMR analysis by considering compound 4-(Thiophen-2-yl) -6-(p-tolyl) - 5,6-dihydropyrimidine-2(1H) -thione, 8 as the representative compound. In its 1H NMR spectra, Ha, Hb and Hc protons of the pyrimidine ring appeared as a doublet of doublet.

IR spectra were run on a Shimadzu FT-IR 8300 spectrophotometer and Perkin Elmer spectrum RXI. 1H-NMR and spectra were recorded in CDCl3 using a Bruker Avance DPX instrument (operating at 250 MHz for 1H). All the coupling constants (J) are in Hertz. Melting points were determined in open capillary tubes in a Buchi-510 oil
