Abstract
Halonitroarylacetic acid esters are prepared by reacting a halonitroaromatic compound with an alpha,alpha-disubstituted acetic acid ester in an inert solvent and in the presence of a base. The halonitroarylacetic acid esters formed by the process can be readily converted into derivatives, such as pharmaceuticals.
