Procedure
2-Aminodecanoic acid (J. Am. Chem. Soc., 1946, 68 450) (16.0 g.) 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 for 2 h., at room temperature, refluxed for 1 h., 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-aminodecanoate (75%) as a colourless oil, b.p. 82°-4° C./0.2 mm.
