Versuchsvorschrift

The present reaction can be carried out in the presence of acetic acid and can be performed by using acetic acid as a solvent. As described in the above Non-patent Document 11, when concentrated sulfuric acid-hydrogen bromide acid is used and 15-pentadecanolide is reacted, for example, 15-(15-bromopentadecyloxy)pentadecanoic acid, which is difficult to get separated from the target compound 15-bromopentadecanoic acid, is produced as a byproduct. As a result, it becomes difficult to obtain highly pure 15-bromopentadecanoic acid.
