Versuchsvorschrift
A round-bottomed flask was equipped with a dry ice-ethanol condenser and immersed in a dry ice-ethanol cooling bath. Ammonia (200 mL) was condensed into the flask followed by the addition of (2R)-2-{[2-amino-5-(benzylthio)[1,3]thiazolo[4,5-d]pyrimidin-7-yl](methyl)amino}pentan-1-ol (5.43 g, 13.9 mmol). The resulting mixture was allowed to warm to −33° C. and sodium metal was added in small pieces until a blue colour appeared and persisted for 30 seconds. The reaction was then quenched by addition of a spoon of solid ammonium chloride. The ammonia was evaporated off and water (250 mL) was added to the residue. The resulting mixture was neutralized with 1M hydrochloric acid (aq.). The precipitated product was collected by filtration, washed with water and acetonitrile and dried in vacuo to yield 3.38 g (81% yield) of the title compound.
