実験手順

A solution of N-(2,2-diphenylethyl)-2-(methylsulfonyl)-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (Preparation 22) (20.1 g, 42.1 mmol) in dry N,N-dimethylformamide (100 ml) was treated with potassium cyanide (5.5 g, 84.6 mmol) and the mixture was heated at 120° C. for 24 hours under a nitrogen atmosphere. The mixture was cooled to room temperature and diluted with water (1000 ml) and stirring was continued for a further 1 hour. The resultant solid was filtered off and washed several times with water. The solid was then dissolved in dichloromethane and the solution was washed with water, dried over anhydrous magnesium sulphate, filtered and evaporated under reduced pressure. The residue was azeotroped with diethyl ether (twice) to afford the title compound as an oil (17 g).
