Procedure
To a solution of 1,1-dimethylethyl {2-[6-cyclopropyl-4-({[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]amino}carbonyl)-1H-pyrazolo[3,4-b]pyridin-1-yl]ethyl}carbamate (260 mg, 0.541 mmol) in DCM (15 mL) was added trifluoroacetic acid (3 ml, 38.9 mmol) and the mixture stirred at room temperature for 2 h. The contents were concentrated in vacuo and the crude residue purified by reverse phase HPLC. (mobile phase: 10 to 70% ACN in H2O, 0.1% NH4OH). The final product was collected as 0.170 g (89%). LCMS E-S (M+H)=353.3 1H NMR (400 MHz, DMSO-d6) δ ppm 1.07 (d, J=6.32 Hz, 4 H), 2.13 (s, 3 H), 2.21 (s, 4 H), 3.00 (t, J=6.19 Hz, 2 H), 4.29-4.47 (m, 4 H), 5.90 (s, 1 H,) 7.43 (s, 1 H), 8.22 (s, 1 H), 8.75 (t, 1 H).
