Lithium Chloride → 3-[6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridine-3-carbonyl]-3,6-diaza-bicyclo[3.2.1]octane-6-carboxylic acid tert-butyl ester

Participants

Reaction Steps

Following general amide formation method 1, 6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-nicotinic acid (in a salt form with 5 eq. of LiCl) (571 mg, 0.942 mmol) was combined with tert-butyl 3,6-diazabicyclo[3.2.1]octane-6-carboxylate (200 mg, 0.942 mmol) to give 446 mg of 3-[6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridine-3-carbonyl]-3,6-diaza-bicyclo[3.2.1]octane-6-carboxylic acid tert-butyl ester in 80% yield. MS (ESI) m/e (M+H+): 588.9.
