Procedure

795 mg of ethyl 3-(3-[(tertiary butoxycarbonyl)amino]methyl-4-hydroxyphenyl)-2-isopropoxypropionic acid was dissolved in 2 ml N,N-dimethylformamide, and 0.3 ml iodoethane and 200 mg potassium carbonate were successively added. After stirring at 50° C. for 4 hours, the reaction mixture was diluted with ethyl acetate, The organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and the solvent was evapoarated. The residue was purified by silica gel column chromatography, and from fractions eluted with hexane-ethyl acetate (8:1), 185 mg of ethyl 3-(3-[(tertiary butoxycarbonyl)amino]methyl-4-ethoxyphenyl)-2-isopropoxypropionate was obtained.
