2-[N-(benzyloxycarbonyl)-N-methylamino]-N-[2-(3-tert-butyl-4-hydroxyphenyl)-1-methylethyl]-3-methylbutanamide → N-[2-(3-tert-butyl-4-hydroxyphenyl)-1-methylethyl]-3-methyl-2-(methylamino)butanamide

Participants

Reaction Steps

A suspension of 0.54 g (1.19 mmol) of 2-[N-(benzyloxycarbonyl)-N-methylamino]-N-[2-(3-tert-butyl-4-hydroxyphenyl)-1-methylethyl]-3-methylbutanamide and 0.10 g of a 20% palladium hydroxide on carbon catalyst in methanol (8 ml) was stirred in a hydrogen atmosphere for 2 hours. After filtering off the catalyst, the solvent was distilled off under reduced pressure to give N-[2-(3-tert-butyl-4-hydroxyphenyl)-1-methylethyl]-3-methyl-2-(methylamino)butanamide in the amount of 0.36 g (95%).
