2-[2-(1,3-Diphenyl-1H-pyrazol-4-yl)-vinyl]-benzo[d][1,3]oxazin-4-one (2) was utilized as a key intermediate for the synthesis of some new quinazolinone derivatives incorporating diphenylpyrazole moiety. Treatment of benzoxazine derivative 2 with different amines, namely, p-phenylenediamine, p-anisidine, p-toluidine, sodiumazide, hydroxylamine hydrochloride, phenyl hydrazine, and hydrazine hydrate afforded pyrazolyl quinazoline derivatives 3, 4, 5, 6, 7, 9, and 10, respectively. Structure 10 was undergoing acetylation and benzoylation with acetic anhydride or benzoyl chloride to afford 11 and 12, respectively. Representative compounds of the synthesized products were established and evaluated as antioxidant and corrosion inhibitors for gasoline lube oils.
