To a solution of 7-cyclopentyl-2-[5-(3,8-diaza-bicyclo[3.2.1]octane-3-carbonyl)-pyridin-2-ylamino]-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (100 mg, 0.205 mmol, 1.0 eq) and Diisopropylethylamine (0.071 mL, 0.409 mmol, 2.0 eq) in CH2Cl2 (5 mL) was added Ethyl Chloroformate (0.022 mL, 0.225 mmol, 1.1 eq) diluted in 3.0 mL of CH2Cl2. The reaction mixture was stirred at 23° C. for 1 hour then diluted with water. The organic was collected and dried over Na2SO4, filtered, and concentrated. The crude reaction was purified using silica gel chromatography which gave 3-[6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridine-3-carbonyl]-3,8-diaza-bicyclo[3.2.1]octane-8-carboxylic acid ethyl ester (25 mg) in 21% yield. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.22-1.37 (m, 4H) 1.60 (br. s., 2H) 1.69-1.82 (m, 3H) 1.97 (br. s., 3H) 2.04-2.20 (m, 4H) 2.56 (d, J=8.59 Hz, 2H) 3.19 (s, 6H) 3.60 (br. s., 2H) 4.21 (q, J=7.07 Hz, 2H) 4.36 (br. s., 2H) 4.56 (br. s., 1H) 4.83 (t, J=8.59 Hz, 1H) 6.52 (s, 1H) 7.82 (dd, J=8.59, 2.02 Hz, 1H) 8.39 (d, J=2.02 Hz, 1H) 8.59 (d, J=8.59 Hz, 1H) 8.77 (s, 1H).
