Abstract
The multiple successive regio- and chemoselective magnesiation of commercially available 2-bromopyrimidine at the C4, C6, and C5 positions allows the regioselective functionalization of all positions of the pyrimidine ring.
Key words
Grignard reagents - pyrimidines - regioselective magnesiation - magnesium bases
