Procedure

To 2-Amino-3-quinolin-4-yl-butyronitrile (1.58 g, 6.42 mmol) in 10 ml of ethanol, ammonia gas was bubbled for 15 minutes. 2 g of Raney Ni (washed with 2×50 ml water and 2×50 ml ethanol) was added to the solution and the reaction mixture was hydrogenated at 50 psi for 2 hours, filtered over celite and concentrated to give 1.54 g (96%) of the product which was then used as such for the subsequent step.

Workup

  1. filtrationfiltered over celite and
  2. concentrationconcentrated
