An efficient three step procedure for the preparation of 6-fluoro-1,2-benzisothiazoles is described. The key step is a regioselective nucleophilic aromatic substitution reaction in which the carbonyl group of a ketone or aldehyde directs nucleophilic displacement to the ortho position in preference to the para position.
