実験手順
Prepared by proceeding in a similar manner to Intermediate 26, starting from methyl 6-amino-3-bromo-2-hydroxybenzoate (prepared according to Wang et al, Bioorg Med Chem Lett 2007 17 2817) and 2-[2-(tert-butyldimethylsilanyloxy)-ethyl]-furan-3-yl-boronic acid (Intermediate 33). The material was used without further characterisation.
