A mixture of 10 g of N-[3-iodophenyl)-4-(tetradecyloxy)benzeneacetamide, 4.96 g of 2-(trimethylstannyl)thiazole, and 638.62 mg of dichlorobis(triphenylphosphine)palladium (II) in 100 ml of tetrahydrofuran is refluxed under argon for 6 hours. The solvent is evaporated and the residue is partitioned between chloroform and 1N sodium hydroxide. The organic layer is dried and evaporated to a yellow solid residue. The residue is purified by chromatography on silica gel using chloroform. A total of 3.5 g of starting material is recovered as well as impure product which is crystallized from hexane:carbon tetrachloride to give 1.8 g of the desired product as a tan solid, m.p. 128°-131° C.
