Procedure

To a solution of 2-methyl-2-(4-nitrophenyl)propanenitrile (0.95 g, 5.0 mmol) in ethyl acetate (10 mL) was added 10% palladium/carbon (100 mg), and the mixture was stirred at room temperature for 14 hr under hydrogen atmosphere. The residual catalyst was filtered through celite, and washed with ethyl acetate. The filtrate was concentrated under reduced pressure to give the title compound (0.81 g, 99%) as a pale-yellow oil.

Workup

  1. filtrationThe residual catalyst was filtered through celite
  2. washwashed with ethyl acetate
  3. concentrationThe filtrate was concentrated under reduced pressure
