Procedure

Into a 200 ml reactor equipped with a reflux condenser and a stirrer, 60 ml of carbon tetrachloride and 10 g of 3-ethylbenzophenone were introduced. While stirring the resultant mixture at room temperature, 8.6 g of N-bromosuccinimide and 0.14 g of benzoyl peroxide were added thereto, and reflux was performed for 8 hours while stirring the reaction solution. After the reaction solution had been cooled to room temperature, the succinimide was filtered out, and carbon tetrachloride was distilled off from a filtrate under a reduced pressure. The spectrum data of the obtained product were in accord with those of 3-(1-bromoethylbenzophenone.
