실험 절차

The synthesis of 6-bromo-2-tetralone is accomplished by dissolving 4-bromophenylacetic acid in methylene chloride and dimethyl formamide, under nitrogen. Oxalyl chloride is added and the mixture is stirred under a positive nitrogen atmosphere to produce the 4-bromo-phenylacetyl chloride, at a yield which typically is better than 99%.
