実験手順

The conversion of benzotriazene derivatives into 4-phenyl quinazolines, such as the transformation of 1,2-diaryl-2-(benzotriazol-1-yl)enamines prepared from lithiated (α-arylbenzotriazol-1-yl)methane and nitriles to afford 2,4-arylquinazolines, and the reaction between 2-(benzotriazol-1-yl)-1,2-diphenylethanone and formamide at 150° C. to afford 50% of 2,4-diphenylquinazoline [41]; and
