Procedure

To a solution of 0.88 g of 6-acetyl-3-acetyloxy-2-ethoxycarbonylpyridine in 8.8-ml of acetic acid was added 0.19 ml of bromine dropwise, and the mixture was stirred at 75° C. for 5 minutes. Evaporation of the solvent gave 0.77 g of 6-(2-bromoacetyl)-2-ethoxycarbonyl-3-hydroxypyridine hydrobromide.
