Procedure

In analogy to the procedure described in example 8 b], 1-fluoro-3-(phenylmethoxy)-benzene (for the preparation of 1-fluoro-3-(phenylmethoxy)-benzene see: A. A. Durrani, J. H. P. Tyman, J. Chem. Soc., Perkin Trans. 1 1979, 8, 2079-2087) was treated with N-bromosuccinimide in the presence of concentrated sulfuric acid to give 1-bromo-2-fluoro-4-(phenylmethoxy)-benzene as colorless oil.
