(S)-tert-butyl((3-bromopyridin-2-yl)(4-(trifluoromethyl)phenyl)methyl)carbamate → (S)-tert-butyl(pyridin-2-yl(4-(trifluoromethyl)phenyl)methyl)carbamate

Participants

Reaction Steps

To a solution of (S)-tert-butyl ((3-bromopyridin-2-yl)(4-(trifluoromethyl)-phenyl)methyl)carbamate (2.24 g, 5.19 mmol) in MeOH (20 mL) was added palladium hydroxide, (20 wt % Pd (dry basis) on carbon, wet, degussa type) (0.365 g, 2.60 mmol). The resulting mixture was then stirred at rt under H2 overnight. The mixture was filtered through Celite® brand filter agent and the solids were washed with a solution of MeOH/EtOAc (1:1, 3×20 mL). The combined filtrates were concentrated and dried to give the desired product as a yellow oil, which was used in the next step without further purification.
