Synthesis of 2-(pyrrolidin-1-yl)pyrimidines by reactions of N-(4,4-diethoxybutyl)pyrimidin-2-amine with (hetero)aromatic C-nucleophiles

摘要

A method was developed for the synthesis of 2-(pyrrolidin-1-yl)pyrimidines and 2-[(4,4-diarylbutyl)amino]pyrimidines by reactions of (hetero)aromatic C-nucleophiles with N-(4,4-diethoxybutyl)pyrimidin-2-amine in the presence of trifluoroacetic acid. The structures of the obtained products were confirmed by methods of IR spectroscopy, H-1 and C-13 NMR spectroscopy, and X-ray structural analysis.
