Ammonia → 2-(Acetamido)-6-(2-aminoethyl)quinoline

Participants

Reaction Steps

Compound 47 (0.060 g, 0.266 mmol) was diluted in absolute EtOH (7 mL) and methanolic ammonia (7 N, 7 mL) was added. Raney nickel (˜1.5 g, washed with H2O and MeOH) was added, and the mixture was degassed and hydrogenated with a balloon at room temperature for 30 min while stirring rapidly. The clear solution was decanted away from the nickel and was filtered through a Pall 0.2 μm syringe filter to remove fine particulate matter. The solution was concentrated and dried in vacuo to yield a colorless gum that became a white semisolid upon standing (0.050 g, 82%). Conversion to this amine was confirmed by 1H NMR spectrometry, TLC, MS, and ninhydrin staining, and it was used crude without any further characterization or purification.
