실험 절차

To a stirred solution of N,N'-bis-(9-fluorenylmethyloxycarbonyl)-D-lysine (12.0 g) in 360 ml of an ethylacetate:dimethylformamide (35:1) mixture are added N-hydroxysuccinimide (3.1 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (5.2 g) and diisopropylethylamine (2.0 ml). After 15 hours the solution is washed successively with dilute hydrochloric acid, water, saturated sodium bicarbonate solution, and brine, dried over magnesium sulfate, and concentrated in vacuo to about 20 ml. The solution is added to hexane (1 l.) and the precipitate is collected and dried to afford the title compound.
