Procedure

A mixture of 2-[chloro(cyclohexyl)methyl]-3,5-dimethyl-1-benzofuran (400 mg) synthesized in Example A90(4), ethyl 3-{[(4-aminophenyl)carbonyl](methyl)amino}propanoate (363 mg) synthesized in Example 2(2), sodium iodide (327 mg), sodium carbonate (231 mg) and N,N-dimethylformamide (10 mL) was stirred at 80° C. for 5 hr. 1N Hydrochloric acid was added to quench the reaction, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (45% ethyl acetate/hexane) to give the title object compound (471 mg, 66%) as a yellow oil.
