Jacobsen radical cyclization of thiobenzanilide (I) in the presence of potassium ferricyanide produced a mixture of the desired benzothiazole (III) and minor amounts of its regioisomer (II). An alternative regiospecific synthesis of (III) consisted in the intramolecular cyclization of the ortho-bromo thiobenzanilide (IV) by means of NaH in hot NMP. Further reduction of the nitro group of (III) using SnCl2 in EtOH gave the desired amino compound.
