Methylamine → 5-Bromo-N-methylpyrimidin-2-amine

Participants

Reaction Steps

40% Aqueous methylamine solution (35 ml) and methanol (20 ml) were added to 5-bromo-2-chloropyrimidine (3 g, 15.5 mmol) and the resulting mixture was heated to reflux for 3 days. The mixture was cooled, then the solvent was evaporated under reduced pressure, the residue was partitioned with methylene chloride and 1 M sodium hydroxide, the organic layer was dried over magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (3.0 g, 100%) as a white solid.
