Synthesis, Spectroscopic Characterization, and Time‐Dependent DFT Calculations of 1‐Methyl‐5‐phenyl‐5H‐pyrido[1,2‐a]quinazoline‐3,6‐dione and Its Starting Precursor in Different Solvents
In this study, 2‐mercapto‐3‐phenyl‐2,3‐dihydro‐1H‐quinazolin‐4‐one (1), which exists as a thiol and thione tautomer, was treated with acetylacetone to give the target compound, namely, 1‐methyl‐5‐phenyl‐5H‐pyrido[1,2‐a]quinazoline‐3,6‐dione (2). The spectroscopic data, including UV/Vis, IR, (1)H NMR...
