反応手順

10 g of HCl are introduced into 200 ml of ethanol. 46 g of ethyl 2-hydroxyimino-4-methyl-3-oxopentanoate are dissolved in this mixture, 5 g of Pd (10% on carbon) are added and the mixture is stirred under an atmosphere of hydrogen (5 bar) for 8 hours. The reaction mixture is filtered through Celite and the solvent is removed under reduced pressure. This gives 45 g of ethyl 2-amino-4-methyl-3-oxopentanoate hydrochloride as a white solid. C8H15NO3*HCl (209.5), MS (ESI)=188 (M+H+).
