Participants

Reaction Steps

Tert-butyl 4-cyano-4-(2,3-dichlorophenyl)piperidine-1-carboxylate (2.30 g, 6.47 mmol) was dissolved in 75 ml of a 7M solution of NH3 in MeOH. Raney Nickel (˜2 g aq. suspension) was added and the mixture shaken on a PARR apparatus under 60 psi of hydrogen for 4 days. The catalyst was removed by filtration through a layer of Celite and the crude reaction mixture concentrated. The crude product (1.90 g yellow oil) was used in the next reaction (amide bond formation) “as is”.
