Versuchsvorschrift
Following Buchwald Procedure A, 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine-6-carbonitrile (95 mg, 0.385 mmol) and 5-(tert-butyl-dimethyl-silanyloxymethyl)-pyridin-2-ylamine (101 mg, 0.424 mmol) (Example C) gave 114 mg of 2-[5-(tert-butyl-dimethyl-silanyloxymethyl)-pyridin-2-ylamino]-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine-6-carbonitrile [following SiO2 chromatography eluting with 1-2% MeOH/dichloromethane and subsequent trituration with diethyl ether].
