The bromination of methyl 3, 4, 5-trimethoxybenzoate by this procedure proceeds smoothly and gives good yields (85%) of product (11). This bromination has been reported several times, but with divergent results. The method reported here leads to a low-melting (34-36') monobromo ester, correctly described by Feist and Dschu,* although if the reaction mixture is heated an unidentified product, mp 88-89', perhaps identical with the material prepared ...
