Vorschrift

A mixture of 4-[4-amino-7-(3-tetrahydrofuryl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]-phenol (0.517 g), 2-fluoro-6-(2-(4-pyridinyl)ethylamino)benzonitrile (0.42 g), potassium carbonate (0.48 g) and dimethylformamide (20 ml) were heated at 120° C. under nitrogen for 8 hours. The mixture was allowed to cool, diluted with water then extracted with ethyl acetate to give a solid which was recrystallised from ethyl acetate to give solid which was purified by flash column chromatography on silica using ethyl acetate and then ethyl acetate/methanol (9:1, 8:1, 4:1) to give 2-[4-(4-amino-7-(3-tetrahydrofuryl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)phenoxy]-6-(2-(4-pyridyl)ethylamino)-benzonitrile, m.p 212-213° C.
