Versuchsvorschrift

To a mixture of 795 parts of dry tetrachloromethane, 40.1 parts of N-bromosuccinimide and a few parts of benzoylperoxide there were added 25 parts of 2,4,5-trimethyloxazole under a nitrogen atmosphere. The whole was stirred for 1 hour at reflux temperature. After cooling in an ice/salt bath, the reaction mixture was filtered and the filtrate was evaporated, yielding 42.7 parts (99.9%) of 5-(bromomethyl)-2,4-dimethyloxazole (interm. 9).
