Product 1

HCID 583154594-[6-(6-cyano-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-[1,4]diazepane-1-carboxylic acid tert-butyl esterYield 49.6%

Procedure

Following Buchwald Procedure A, 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine-6-carbonitrile (95 mg, 0.385 mmol) and 4-(6-amino-pyridin-3-yl)-[1,4]diazepane-1-carboxylic acid tert-butyl ester (124 mg, 0.424 mmol) gave 4-[6-(6-cyano-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-[1,4]diazepane-1-carboxylic acid tert-butyl ester (96 mg) [following SiO2 chromatography, eluting with a 1-3% MeOH/dichloromethane and subsequent trituration with a diethyl ether]. The material is used directly in the next step.
