実験手順

6-Chloro-9H-purin-2-amine (5.0 g., 29.5 mmole) was added to 47% hydrogen iodide (61 ml., 12.2 ml./g.) chilled in an ice bath. After 1.5 hours, water (61 ml.) was added and the mixture stirred in an ice-bath for 30 minutes. The yellow solid was filtered out and the filter cake was washed with water. The wet solid was transferred to a beaker and the residue in the funnel was washed into the beaker with water (30 ml.). 6M Sodium hydroxide (7 ml.) was added with stirring until all the solid had dissolved (pH 14). The solution was added to boiling water (30 ml.) containing acetic acid (3 ml.). The mixture was boiled briefly and allowed to stand at room temperature for one hour. The product was filtered off, washed with water, and dried under vacuum overnight to give 6.88 g. of the desired product; m.p. about 240° C. (dec.).
