실험 절차

Ethanol (150 mL) was cooled to 0° C., and thionyl chloride (16.57 mL, 139.3 mmol) was added over a period of ten minutes. The reaction was stirred for ten minutes at 0° C., and 12-aminododecanoic acid (25.0 g, 116 mol) was then added. The reaction was allowed to warm to ambient temperature, stirred at a slightly elevated temperature for one hour, and stirred at ambient temperature for two hours. The Ethanol was removed under reduced pressure, and the solid residue was recrystallized from ethyl acetate. The crystals were isolated by filtration, washed with diethyl ether, and dried under vacuum to provide 37.4 g of ethyl 12-aminododecanoate hydrochloride as a white solid.
