4-(4-Nitrophenyl)-1-(3,3,3-trifluoropropyl)-1,2,3,6-tetrahydropyridine → 4-[1-(3,3,3-Trifluoropropyl)piperidin-4-yl]aniline

Participants

Reaction Steps

In Paar autoclave, a solution of 4-(4-nitrophenyl)-1-(3,3,3-trifluoropropyl)-1,2,3,6-tetrahydropyridine (2.6 g; 8.66 mmol; 1.0 eq.) in EtOAc (52 mL) was hydrogenated at 25 bars O/N in presence of Pd/C (moistened, 10%, 0.26 g; 2.44 mmol; 0.28 eq.). Reaction mixture was filtered through a celite pad. Filtrate was then concentrated under reduced pressure to give the title compound as a brown oil (2.33 g, 99%). UPLC/MS: (MS+) 273.4.
