Azobisisobutyronitrile → 2-Bromomethyl-6-hydroxy-benzoic acid ethyl ester

Participants

Reaction Steps

2-Hydroxy-6-methyl-benzoic acid ethyl ester (4.046 g), NBS (4.786 g), and AIBN (1.134 g) were weighed into a round-bottom flask equipped with a reflux condenser. CCl4 (40 mL) was added and the mixture was heated at reflux for 2 h. After cooling to RT, solid was removed by filtration and the filtrate was concentrated to give a yellow oil as crude, which solidified upon standing. The crude was purified by silica gel chromatography (300 g, 0-5% EtOAc/hexanes) to afford 2-bromomethyl-6-hydroxy-benzoic acid ethyl ester as a white solid.
