Procedure

To 0.55 grams (0.96 mmoles) of 3-[6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-4-oxo-3,9-diaza-bicyclo[4.2.1]nonane-9-carboxylic acid tert-butyl ester was added 15 ml of ethyl acetate. The mixture was stirred at room temperature under N2 and cooled to ice bath temperature. To this mixture was added 5 mls 4N HCl in dioxane. The resultant mixture was allowed to stir until all starting material was consumed. The resultant mixture was stirred until all starting material was consumed as determined by HPLC-MS. To this mixture was added 50 ml of a 1:1 mixture of ethyl acetate/diethyl ether to precipitate solids. The solids were filtered and washed with excess 1:1 mixture of ethyl acetate/diethyl ether and dried under vacuum to a constant weight to yield 7-Cyclopentyl-2-[5-(4-oxo-3,9-diaza-bicyclo[4.2.1]non-3-yl)-pyridin-2-ylamino]-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide as the di-hydrochloride salt, 0.213 grams (45% yield).
