Reaktionsschritte
A solution of 2-aminoisobutyric acid (3.3 g, 32 mmol) in absolute ethanol (100 mL) was cooled to −78° C. and HCl(g) bubbled in for 10 minutes. The flask was sealed with a septum and stirred at ambient temperature. After 14 hours the mixture was concentrated in vacuo to afford 5.3 g (99% yield) of ethyl 2-aminoisobutyrate as a white solid; NMR (CDCl3) 8.9 (br s, 3), 4.1 (q, 2), 1.7 (s, 6), 1.3 (t, 3) ppm.
