Reaction Steps

By the method of Tetrahedron, 1992, 48, 8127-8142 the substance 5-(2,6-dichlorophenyl)-3-(4-nitrophenyl)isoxazole can be treated with diphosphorus pentasulfide followed by aqueous or ethanolic ammonia quench to produce 5-(2,6-dichlorophenyl)-3-(4-nitrophenyl)isothiazole. The nitrophenyl group can be reduced to the corresponding aniline with tin (II) dichloride or iron powder and ammonium chloride. This aniline can then be treated with 2,2-dichloroacetyl chloride and triethylamine to yield 2,2-dichloro-N-[4-[5-(2,6-dichlorophenyl)-3-isothiazolyl]phenyl]acetamide.
