Microbial hydroxylation of o-bromophenylacetic acid provided 2-bromo-5-hydroxyphenylacetic acid. This enabled a route to the key intermediate 4-bromo-2,3-dihydrobenzofuran for synthesizing a melatonin receptor agonist and sodium hydrogen exchange compounds. Pd-mediated coupling reactions of 4-bromo-2,3-dihydrobenzofuran provided easy access to the 4-substituted-2,3-dihydrobenzofurans.
