Reaction Steps

334 mg of ethyl 3-(3-[(tertiary butoxycarbonyl)amino]methyl-4-[(trifluoromethyl)sulfonyl]oxyphenyl)-2-isopropoxypropionate was dissolved in 4 ml dioxane. 280 mg of 2-tributylstannylfuran, 75 mg of tetrakistriphenylphosphine palladium and 83 mg of lithium chloride were added thereto, followed by stirring overnight at 80° C. in a nitrogen atmosphere. The reaction mixture was concentrated and the residue was purified by silica gel column chromatography, to give 180 mg of ethyl 3-(3-[(tertiary butoxycarbonyl)amino]methyl-4-[(trifluoromethyl)sulfonyl]oxyphenyl)-2-(2-furyl)propoxypropionate from fractions eluted with hexane-ethyl acetate (7:1).
