methoxide-catalyzed ring closure gives the corresponding 3-methyl-2-phenylquinazoline-4-thiones. These compounds were characterized by means of their 1H- and 12C-NMR spectra. The kinetics of the cyclization reaction has been followed with UV-VIS spectroscopy at 100 °C in methanolic solutions of sodium methoxide.
