Following deprotection method 1, 3-[6-(7-Cyclopentyl-6-dimethylcarbamoyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)-pyridin-3-yl]-4-oxo-8-oxa-3,10-diaza-bicyclo[4.3.1]decane-10-carboxylic acid tert-butyl ester (470 mg, 0.777 mmol) was converted to 7-Cyclopentyl-2-[5-(4-oxo-8-oxa-3,10-diaza-bicyclo[4.3.1]dec-3-0)-pyridin-2-ylamino]-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (231 mg, 0.457 mmol) in 58.8% yield. 1H NMR (400 MHz, D6 DMSO) δ 10.2 (s, 1H, broad), 9.05 (s, 1H, broad), 8.35 (s, 1H), 8.0 (d, 1H), 7.7 (d, 1H), 6.9 (s, 1H), 4.82 (m, 1H, broad), 4.6 (d, 1H), 4.25 (s, 1H, broad), 4.15 (s, 1H, broad), 3.82 (m, 1H, broad), 3.5 (d, 1H), 3.05 (s, 6H), 2.82 (m, 1H), 2.3 (m, 2H), 2.2-1.95 (m, 10H, broad), 1.89 (m, 1H), 1.65 (m, 2H) MS m/z 504.6 (M+H)
