Abstract
A method for producing a (2-methylpyrimidin-5-yl)boronic acid derivative (3) includes the step of decarboxylating a 5-bromopyrimidine derivative (1) to synthesize 5-bromo-2-methylpyrimidine (2). The method enables efficient production of 5-bromo-2-methylpyrimidine (2) with less environmental impact, leading to efficient production of (2-methylpyrimidin-5-yl)boronic acid derivative (3) which is useful as a pharmaceutical intermediate.
