Methane → 3-Amino-1-chloro-3-methylpentan-2-one hydrochloride

참여 물질

반응 단계

In a 2 L Parr™ bottle was placed 41 g of 3-amino-1,1-dichloro-3-methyl-2-pentanone hydrochloride, 0.8 g of 10% palladium over charcoal, and 400 mL of ethanol. The resulting mixture was shaken in a Parr™ apparatus at 50 psi for 3 hours. The crude reaction mixture was filtered through Celite™ and evaporated in vacuo yielding a viscous oil, which was taken in 300 to 400 mL of ethyl acetate and stirred at room temperature for several hours. The expected 3-amino-1-chloro-3-methyl-2-pentanone hydrochloride crystallized as a white solid; 300 mL of hexane was added to the resulting suspension and filtered yielding 34 g (98%) of the expected 3-amino-1-chloro-3-methyl-2-pentanone hydrochloride.
