Participants

Reaction Steps

A mixture of benzyl (5-n-butyl-2-pyridyl)carbamate (6.5 g. 22.86 mmoles) and 10% palladium on carbon (2.7 g.) in ethanol (400 ml.) was shaken at room temperature for 2 hours in an atmosphere of hydrogen at an initial pressure of 3.52 kg./cm.2The mixture was filtered and the filtrate reduced to dryness to leave 2-amino-5-n-butylpyridine (3.42 g., 99.7%), m.p. 30°-33° (lit. m.p. 35°-36° in Helv.
