Microwave-assisted simple synthesis of 2-anilinopyrimidines by the reaction of 2-chloro-4,6-dimethylpyrimidine with aniline derivatives
2-anilinopyrimidines including novel derivatives has been obtained from 2-chloro-4,6-dimethylpyrimidine by aromatic nucleophilic substitution with differently substituted anilines under microwave conditions. The substituents had a significant impact on the course and efficiency of the reaction. The results reported herein demonstrate the efficacy of microwaves in the synthesis of the title heterocyclic compounds
LiAlH4 and NaBH4 were found to mediate the conversion of 2-(pyrimidyl-2-ylsulfanyl)-N-arylbenzamides and 2-(triazinyl-2-ylsulfanyl)-N-arylbenzamides into pyrimidyl and triazinyl amines under notably mild conditions via a novel reductive rearrangement mechanism. These reactions invent a newroute to prepare amines, which are a kind of important biologically active compounds and provide the first insight
