HCID 534200525-Bromo-3-(bromomethyl)pyridin-2-amine hydrobromide

Procedure

A solution of 2-amino-5-bromo-3-(hydroxymethyl)pyridine (34.6 g, 170.0 mmol) in hydrobromic acid (48% in H2O, 93 mL) was stirred at reflux overnight. The reaction mixture was cooled to room temperature, the precipitated product filtered and washed with H2O (100 mL) and dried. The title product was obtained as a light yellow solid (36.1 g, 56%, py 96.5%).
