PRODUCTION OF HYDROGEN BROMIDE AND BROMINE ADDUCT OF PYRIDINE COMPOUND

摘要

PURPOSE:To produce the titled compound useful as a mild and highly selective bromination agent, in high yield, by using an alcohol such as methanol, ethanol, propanol, butanol, etc. as a solvent for the reaction of a pyridine compound with hydrogen bromide and bromine. CONSTITUTION:In the production of an addition compound of hydrogen bromide and bromine to a pyridine compound by the reaction of a pyridine compound with hydrogen bromide and bromine, a 1-8C alcohol, especially methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol or their mixture, especially preferably methanol, is used as the reaction solvent. EFFECT:Smooth and efficient reaction process.
