tert-butyl ((1S,2S)-2-((5-(trifluoromethyl)-3-vinylpyrazin-2-yl)amino)cyclopentyl)carbamate → tert-butyl ((1S,2S)-2-((3-ethyl-5-(trifluoromethyl)pyrazin-2-yl)amino)cyclopentyl)carbamate

Participants

Reaction Steps

To a solution of tert-butyl N-[(1S,2S)-2-{[3-ethenyl-5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]carbamate (460 mg, 1.24 mmol) in methanol (12 ml) was added palladium on carbon (10% wt, 50% wet) (131 mg, 0.124 mmol) and the resulting mixture was stirred under a balloon of hydrogen gas for 2 hours. The reaction was filtered through diatomaceous earth (commercially sold under the trade mark “Celite”). To this was then added further palladium on carbon (10% wt, 50% wet) (131 mg, 0.124 mmol) and the resulting mixture was stirred under a balloon of hydrogen gas for 72 hours. The reaction was filtered through diatomaceous earth (commercially sold under the trade mark “Celite”) and concentrated in vacuo to afford the title compound.
