Procedure

2-Aminodecanoic acid (J. A,. Chem. Soc., 1946, 68, 450)(16.0g) was added in portions to a cooled (-10° C.) mixture of absolute ethanol (70 ml) and thionyl chloride (6 ml) with stirring. The resulting solution was set aside of 2 hours, at room temperature, refluxed for 1 hour, cooled, poured into ice-water, and the pH of the solution was adjusted to 9 with aqueous sodium hydroxide. The mixture was extracted with ether, the extract was dried, concentrated, then distilled, giving ethyl 2-amino-decanoate (75%) as a colourless oil, b.p. 82°-4°C/0.2 mm.
