Methods are proposed for preparation of 5- and 6-substituted 2-methylbenzothiazoles by reactions of organozinc and organotin compounds with 5- and 6-bromo-2-methylbenzothiazoles, catalyzed by palladium complexes. The reactions of organozinc compounds with 5(6)-bromo-2-methylbenzothiazoles occur in THF at 20°C in the presence of PdCl2(dppf), and those of organotin compounds are carried out in DMF, aqueous DMF, or water at 40-100°C in the presence of PdCl2, Pd(OAc)2, or PdCl2(PPh3)2.
