Quinazolines

A method was developed for the preparation of 2,3-polymethylene-3,4-dihydro-4-quinazolones with substituents in the benzene and polymethylene chains by reaction of anthranilic acid and its substituted derivatives with -butyro-, 5-phenyl--butyro-, -capro-, and -chloro--caprolactams in the presence of dehydrating agents. The corresponding quinazolines were obtained by reduction of the synthesized quinazolones.See [1] for communication V.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1564–1569, November, 1976.
