実験手順
A mixture of 11.8 parts of 2-chloro-m-tolyl 2-thienyl ketone, 8.9 parts of N-bromosuccinimide, 100 parts of carbon tetrachloride and 0.25 parts of benzoyl peroxide is stirred and refluxed for 2 hours. The precipitated succinimide if filtered off and washed on the filter which carbon tetrachloride. The filtrate is dried and evaporated, yielding α-bromo-2-chloro-m-tolyl 2-thienyl ketone as a residue.
