Reaction Steps

A mixture of 20% Pd(OH)2 on carbon (0.3 g) and 1-benzyl-3,3,5-trimethyl-4-piperidone (1.5 g, 6.5 mmol) in methanol (20 ml) was stirred in hydrogen atmosphere (1 atm.) at 30° C. for 6 hr. The catalyst was filtered off, washed with methanol and filtrate was concentrated to dryness to afford 3,3,5-trimethyl-4-piperidinone. Yield 0.8 g (88%), C8H15NO, m/z 142 (M+1).
