Procedure

To a mixture of 6.2 parts of ethyl 5-methyl-2-oxazolecarboxylate and 191 parts of dry tetrachloromethane there were added 7.1 parts of N-bromosuccinimide and a few parts of benzoylperoxide under a nitrogen atmosphere. The whole was stirred for 1 hour at reflux temperature. After cooling, the reaction mixture was filtered and the filtrate was evaporated, yielding 11 parts (100%) of ethyl 5-(bromomethyl)-2-oxazolecarboxylate (interm. 21).
