Procedure
4-Nitrobenzonitrile and 2,6-dichlorophenyl methyl ketone can be reacted with phenyliodine (III) diacetate and trifluoromethylsulfonic acid by the method of R. S. Varma, et al, J. Heterocyclic Chem., 1998, 35(6), 1533–1534 to give 5-(2,6-dichlorophenyl)-2-(4-nitrophenyl)-1,3-oxazole. The nitrophenyl group can be reduced to the corresponding aniline with tin (II) dichloride or iron powder and ammonium chloride. Reaction of this aniline with 2,2-dichloroacetyl chloride and triethylamine can then give 2,2-dichloro-N-[4-[5-(2,6-dichlorophenyl)-2-(1,3-oxazolyl)]phenyl]acetamide.
