ABSTRACT:
This invention relates to methods of making pyrimidinyl-substituted imidazole compounds by sequential substitution of the 4- and 2-chloro groups of 2,4-dichloropyrimidine, nucleophilic substitution to form pyrimidinylalkyne derivatives, oxidation to the corresponding 1,2-diketones, and cyclocondensation reactions.
