Versuchsvorschrift
5.0 g (43.4 mmol) of methyl 3-aminocrotonate, 70 ml of a 9.3% strength solution of 17 g (43 mmol) of HCl gas in anhydrous methanol and 0.22 g of Pt/C catalyst (Heraeus K0129) were introduced into a 160 ml Parr autoclave. The hydrogenation was carried out for 3 hours at 21-25° C. under 5-10 bar of hydrogen. The catalyst was then filtered off and the solvent was completely removed by distillation on a rotary evaporator. 6.34 g of pure methyl (RS)-3-amino-butyrate hydrochloride were obtained as an oil.
