Reaction Steps

To a solution of 6-(7-cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-nicotinic acid (100 mg, 0.25 mmol) (Example D) in 3 mL of DMF is added dimethyl-piperidin-4-yl-amine (33 mg, 0.25 mmol), HBTU (140 mg, 0.38 mmol), and DIPEA (0.088 mL, 0.51 mmol). Alter 48 h stirring at room temperature, the resulting mixture is concentrated and diluted with saturated NaHCO3 and extracted with ethyl acetate (3×100 mL). The combine organics are dried over Na2CO3 and concentrated to give a reddish residue. Preparative HPLC to give 7-cyclopentyl-2-[5-(4-dimethylamino-piperidine-1-carbonyl)-pyridin-2-ylamino]-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (60 mg, 46%).
