Description	The intramolecular cycloaddition reaction of N1-R- or N1,N1-Di-R-N3-[[(2-cyanophenyl)imino](phenyl)-methyl]thioureas formed in situ by addition of amines to N2-(2-cyanophenyl)-N1-thioxo-methylidenebenzene-1-carboximidamide 1 were investigated. These thioureas undergo cyclization folowed by Dimroth rearrangement and quinazolin-4-yl or quinazolin-4-ylidene thioureas were identified.
