Versuchsvorschrift

A solution of 6-[(2,2-diphenylethyl)amino]-9-tetrahydro-2H-pyran-2-yl-9H-purine-2-carbonitrile (5.70 g, 13.18 mmol) (Preparation 5) in ethanol (200 ml) saturated with ammonia gas was treated with Pearlmann's catalyst (1.00 g), pressurised to 60 psi with hydrogen in a sealed vessel and stirred at room temperature for 30 hours. The mixture was filtered through a pad of Arbocel (trade mark) and the solvent was removed under reduced pressure. The residue was azeotroped from dichloromethane (×2) and then purified by column chromatography on silica gel eluting with dichloromethane:methanol (95:5 by volume) gradually changing to dichloromethane:methanol:0.88 ammonia (90:10:0.5 by volume) to afford the title compound (4.34 g).
