実験手順

To a solution methyl 6-amino-5-bromopyridine-2-carboxylate (20.04 g) in acetic acid (900 ml) was added N-chlorosuccinimide (13.96 g) and the resultant solution was heated to 120° C. for 1 hour. The solution was then evaporated and treated with excess aqueous sodium bicarbonate and extracted with dichloromethane. The organic fraction was dried and evaporated to give the product (21.98 g).
