Abstract

The reaction of 2-chloro-4-methylthioquinazoline with alkylamines in dimethylformamide afforded 2,4-bis(methylthio)-, 2-alkylamino-4-methylthio-, 4-alkylamino-2-chloro-, 4-alkylamino-2-methylthio-, and 2,4-bis(alkylamino)quinazoline. The relative easiness of displacement of the chlorine and/or the methylthio group in 2-chloro-4-methylthioquinazoline depended on the bulkiness of alkylamines.
