The resulting solution was refluxed for 2 h, cooled to room temperature and concentrated in vacuo. The residue was diluted with AcOEt and washed twice with 2N aqueous NAOH solution then brine, dried over MGS04 and concentrated in vacuo to give 3-bromo-5-iodo-benzoic acid methyl ester (D8a) (14.8 g, 97percent) as a pale brown solid.
