Reaction Steps

To a solution of 7-cyclopentyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (100 mg, 0.230 mmol) and cyclopropanecarbonyl chloride (22 mL, 0.690 mmol) in 5 mL of CH2Cl2 is added a solution of Et3N (64 mL, 0.459 mmol) and stirred at rt for 18 h. 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 preparative HPLC to give 2-[5-(4-carbamoylmethyl-piperazin-1-yl)-pyridin-2-ylamino]-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (81 mg, 68%).
