Versuchsvorschrift

Amino(pyrimidin-5-yl)acetonitrile (1.1 g, 8.2 mmol) is hydrolyzed by refluxing in a small volume of dilute HCl for 1 hour. The pH is raised to 10 by addition of saturated sodium carbonate and the mixture then extracted with chloroform. Evaporation of the chloroform and chromatography (silica, chloroform/methanol) gives product as a yellow solid 950 mg (81%) ms m/z=142.
