Abstract
The present invention relates to a preparation method for pyrimidine-2-amine and, more specifically, to a method for preparing a pyrimidine-2-amine compound via a pyrimidine-2-iminium salt intermediate by using a nucleophilic imine-type reagent, in which various amino functional groups are selectively introduced at position No. 2 of pyrimidine.
