実験手順
To solution of 4-acetylamino-3-chloro-6-iodopyridine-2-carboxylic acid, methyl ester (5.0 g, 14 mmol) in methanol (25 mL) was added acetyl chloride (1 mL) and the solution heated under reflux for 1 hour. The solution was cooled and water (25 mL) added and the precipitate was collected. Recrystallization from methanol gave 4-amino-3-chloro-6-iodopyridine-2-carboxylic acid, methyl ester (3.5 g, 11 mmol) mp 152-153° C.
