Reaction Steps

Following general amide formation method 1, 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) was combined with BOC-Proline (48.5 mg, 0.225 mmol, 1.1 eq) which gave 2-{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-carbonyl}-pyrrolidine-1-carboxylic acid tert-butyl ester (95 mg) in 64% yield. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.36-1.57 (m, 12H) 1.63-1.86 (m, 5H) 1.91 (br. s., 4H) 1.99-2.29 (m, 10H) 2.45-2.67 (m, 2H) 3.18 (s, 7H) 3.43 (d, J=6.57 Hz, 2H) 3.60 (br. s., 3H) 4.42 (br. s., 2H) 4.56 (br. s., 2H) 4.68-4.94 (m, 2H) 6.53 (s, 1H) 7.83 (d, J=8.08 Hz, 1H) 8.41 (br. s., 1H) 8.58 (d, J=8.59 Hz, 1H) 8.76-8.80 (m, 1H).
