Reaction Steps

To a solution of 67 mg 2-{[1-(2-hydroxy-ethoxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester and 29 mg 3,5-difluorophenol in 1 ml THF at 0° C. 58 mg triphenyl phosphine and 46 μl diisopropylazodicarboxylate were added. After 16 h at room temperature the reaction was concentrated in vacuo and after chromatography on silica (ethyl acetate/heptane) 80 mg 2-({1-[2-(3,5-difluoro-phenoxy)-ethoxy]-naphthalene-2-carbonyl}-amino)-2-methyl-propionic acid methyl ester were obtained.
