실험 절차

To a solution of 10.80 g (0.060 mole) of 3-(4-methoxyphenyl) propanoic acid and 6.57 g (0.065 mole of triethylamine in 25 ml dichloromethane at about 0.5° C., 6.84 g (0.063 mole) of ethyl chloroformate was added dropwise. The mixture was stirred for about 15 minutes at a temperature of about 5° to 10° C., then 6.96 g (0.065 mole) of benzylamine were added. The resulting mixture was stirred for about thirty minutes, and the solvent was evaporated. The residue was slurried in 5% aqueous sodium hydroxide. The solid was collected by filtration and rinsed with water until neutral. The washing process was repeated using 5% hydrochloric acid. The residue was dried under vacuum to give 11.0 g of the above-identified product, melting point 92°-94° C., which was suitable for use in step (b).
