Abstract

The reaction of 2,4(1H,3H)-quinazolinedione (1) with N-alkylpyrrolidine in phosphoryl chloride undergoes readily the reaction of a von Braun type through the formation of dichlorophosphate and a quaternary ammonium salt in sequence, which decomposes to give 2-(N-alkyl-4-chlorobutylamino)-4-chloroquinazoline (3). A conceivable reaction mechanism is discussed.
