実験手順

Methyl 6-[(2,2-diphenylethyl)amino]-9-tetrahydro-2H-pyran-2-yl-9H-purine-2-carboxylate (Preparation 9) (100 mg, 0.22 mmol) and 1-(2-aminoethyl)piperidine (0.31 ml, 2.19 mmol) were heated together at 130° C. for 2 hours. The excess amine was removed under reduced pressure and the residue was purified by column chromatography on silica gel eluting with dichloromethane:methanol (95:5 by volume) to afford the title compound as a yellow foam (104 mg).
