2 Molar hydrochloric acid (10 ml) was added to a stirred solution of 6-(phenethylamino)-9-tetrahydro-2H-pyran-2-yl-9H-purine-2-carbonitrile (10.2 g, 27.6 mmol) (preparation 44) in ethanol (250 ml) at 60° C. The solution was allowed to cool to room temperature and the white solid that had been formed filtered off. After drying, this gave the title compound (6.1 g) as a white crystalline solid. MS: 265 (MH+).
