2-Hydroxy-N,N-dimethyl-2-{5-[3-oxazol-2-yl-1(2-trimethylsilanyl-ethoxymethyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyridin-3-yl}-acetamide (10 mg, 0.02 mmol) was stirred in dichloromethane/trifluoroacetate acid (1 ml/1 ml) at room temperature for 2 hours. The solvents were removed under vacuum and the crude was stirred in dichloromethane/ethylenediamine (1 ml/1 ml) for 2 hours at room temperature. Again the solvents was removed under vacuum and the crude was dissolved in DMSO, filtered and purified by reverse phase HPLC, lyophilized afforded 2-hydroxy-N,N-dimethyl-2-{5-[3-oxazol-2-yl-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyridin-3-yl}-acetamide (2 mg, 31% yield). 1H NMR (500 MHz, DMSO-d6) δ 2.81 (s, 3H), 2.96 (s, 3H), 5.58 (s, 1H), 6.22 (s, 1H), 7.28 (s, 1H), 8.04 (t, 1H), 8.76 (s, 1H), 8.22 (s, 1H), 8.52 (d, 1H), 8.62 (s, 2H0, 8.83 (d, 1H). MS: m/z 364.0 (M+H+).
