Procedure

To a solution of 12 2-[5-(4-tert-Butoxycarbonyl-piperazin-1-yl)-pyridin-2-ylamino]-7-cyclopentyl-5-methyl-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid (120 mg, 0.23 mmol), HBTU (130.9 mg, 0.345 mmol) and HOAt (46.97 mg, 0.345 mmol) in dry DMF (15 mL) is added a solution of acetic hydrazide (34.09 mg, 0.46 mmol) and diisopropylethylamine (121 ul, 0.693 mmol) in dry DMF (5 mL). The reaction mixture is stirred at room temperature overnight. The reaction mixture is diluted with water and extracted with ethyl acetate three times. The organic layers are combined, washed with brine and dried over anhydrous sodium sulfate. The solvent is evaporated and the crude product is purified by preparative HPLC to give 4-{6-[6-(N′-Acetyl-hydrazinocarbonyl)-7-cyclopentyl-5-methyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino]-pyridin-3-yl}-piperazine-1-carboxylic acid tert-butyl ester as a yellow solid (120 mg, 75.4%). [M+H]+=578.32.
