5-Arylpyrrole-2-carboxylic acids are important keyintermediates in the synthesis of HIV-1 entry inhibitors (such as NBD-11021 and NBD-14010). Here we present a general method for the synthesis of some 5-arylpyrrole-2-carboxylic acids in three steps starting from pyrrole. By this method, the compounds could be prepared on gram scale and without chromatographic purification. 5-Arylpyrrole-2-carboxylic acids are important
