Reaction of quinazoline-2,4(1H,3H)-dione with N-substituted cyclic amines in combination with phosphoryl trichloride
摘要:
The reaction of quinazoline-2,4(1H,3H)-dione with N-allyl, N-benzyl and N-methyl cyclic amines in combination with phosphoryl trichloride in the presence of tripropylamine in 1,4-dioxane afforded 4-chloro-2-(cycloalkylamino)quinazolines. In the case of N-substituted pyrrolidines, 4-chloro-2-(N-substituted 4-chlorobutylamino) quinazolines were also obtained.
