Procedure

Compound 4 (2.0 g, 2.1 mmol, 1.0 eq.) was dissolved in anhydrous dichloroethane (30 mL) and then Cs2CO3 (1.7 g, 5.2 mmol, 2.5 eq.) was added. The reaction medium was then slowly heated to reflux. The mixture was stirred for 12 hrs. upon reflux then cooled to room temperature, filtered and the solvent was removed under vacuum. The residual oil then was purified by column chromatography (DCM/hexanes 80/20). The product was further recrystallized to give 2-(4-(4-(2-chloroethoxy)-3,5-diiodophenoxy)-3,5-diiodophenyl)-N-cyclohexylacetamide, compound 15, (94 mg, 0.1 mmol) as a powder.
