Reaction Steps

A mixture of 5-chloro-2-hydroxypyridine (100 g) and bromine (40.1 mL) in acetic acid (400 mL) was stirred at r.t. for 1 h. The mixture was poured into 3 L of water and stirred for 30 min then filtered. The residual solid was washed with 2 L of cold water, air dried and then coevaporated with toluene three times and with benzene two times. The white solid (81 g) so obtained was used in the subsequent reaction.
