Abstract

A study of the reaction of quinazoline derivatives with acid chlorides in the absence of acids has shown that alkyl 2-(4,4-diphenyl-1,2,3,4-tetrahydro-2-quinazolinylidene)acetates undergo C-acylation. The molecular structure of methyl  2-(4,4-diphenyl-1,2,3,4-tetrahydro-2-quinazolinylidene)-3-oxobutanoate has been investigated by X-ray analysis.
