Versuchsvorschrift

To a 500 mL 3 neck round bottom flask equipped with a magnetic stirrer, temperature probe and nitrogen inlet was added 2-amino-6-chloropurine (20 g), sodium hyroxide (28 g) and benzyl alcohol (200 mL). The mixture was stirred for 20 minutes and then heated at 100° C. for 2-3 hours. The reaction mixture was then cooled to room temperature and partitioned between methyl t-butyl ether (300 mL) and water (300 mL). The aqueous layer was separated and the pH was adjusted to 7-8 with 6 M HCl. The resulting solid was filtered, washed with water (50 mL) and dried under vacuum at 50° C. for 20 hours to provide the desired product as a pale yellow solid (24.3 g).
