Procedure
11 g of thionyl chloride was added to 14.5 g (0.046 mol) of the 3-bromo-4-n-heptyloxybenzoic acid prepared in Step II and was gently refluxed for two hours. Excess thionyl chloride was removed by distillation or vacuum distillation to yield 14.2 of 3-bromo-4-n-heptyloxybenzoyl chloride. The yield was calculated to be 92.3%.
