실험 절차

A mixture of 5.24 g. of α-aminoisobutyric acid, 50 ml. of pyridine, and 25 ml. of H2O was stirred while 21.1 g. of 4-(hexadecylamino)benzoyl chloride hydrochloride was added. The mixture was stirred for 18 hours at ambient temperature and filtered. The filtrate was evaporated and the residual yellow glass was dissolved in 1N NaOH solution. The solution was extracted with diethyl ether and then acidified with 6N HCl. The precipitate was collected, dried, and recrystallized from acetone, melting point 199°-202° C.
