الإجراء التجريبي
A stirred suspension of 2,6-dichloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (Intermediate 1 in WO03/080613) (1.14 kg) in n-butanol (1.7 L) was treated with trans-1,4-diaminocyclohexane (239.2 g) and di-iso-propylethylamine (2.5 L), then heated at 75° C. for 17 hours. The suspension was allowed to cool to ambient temperature, filtered, washed with n-butanol (2×2.3 L) and dried in vacuo at 60° C. to give the title compound (0.9 kg).
