Versuchsvorschrift

Sodium hydride (120 mg, of a 60% dispersion in mineral oil) was added to a solution of 4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine (906 mg) and dimethylformamide (30 ml) with stirring under nitrogen. The mixture was stirred for 30 minutes and then a solution of 3-(tosyloxy) tetrahydrofuran (750 mg) in dimethyl formamide (10 ml) was added with stirring. The mixture was stirred and heated at 95° C. for 18 hours and then evaporated under vacuum. The residue was partitioned between ethyl acetate and water. The ethyl acetate layer was separated, dried and evaporated to give a residual gummy solid which was triturated with ether and filtered to give 5-(4-phenoxyphenyl)-7-(3-tetrahydrofuryl)-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine m.p. 196-196.5° C.
