Polycyclic N-Heterocyclic Compounds, Part 68: Reactions of 3-(2-Bromoethyl)quinazolin-4(3H)-one and 3-(2-Bromoethyl)-5,6,7,8-tetrahydroquinazolin-4(3H)-one with Primary Alkylamines via a Dimroth-Type Rearrangement
2011
Abstract The reaction of 3-(2-bromoethyl)quinazolin-4(3H)-one with ethyl- and n-propylamine gave abnormal fused 3-alkyl-4-alkyliminoquinazolines via a Dimroth-type rearrangement, as well as normal substituted 3-(2-alkylaminoethyl) derivatives in methanol. The reaction of 3-(2-bromoethyl)-5,6,7,8-tetrahydroquinazolin-4(3H)-one with primary alkylamines was also investigated for the scope of this rearrangement reaction.
