実験手順

To a stirred solution of 3-(4-iodophenyl)propanoic acid (commercially available) in toluene and methanol (9:1, 0.2 M) 0° C. was added (diazomethyl)trimethylsilane (1 N solution in Et2O, 2 eq). After stirring at room temperature overnight the reaction mixture was concentrated under vacuum and the resulting crude residue was purified by chromatography (silica gel, 20-50% EtOAc in hexanes) to afford methyl 3-(4-iodophenyl)propanoate.
