Reaction Steps

tert-Butyl 3-{[5-chloro-4-(2,5-dichloro-3-cyanophenoxy)-1H-1,2,3-benzotriazol-1-yl]methyl}-1H-pyrazolo[3,4-b]pyridine-1-carboxylate (569 mg, 0.997 mmol) was dissolved in TFA (5 mL). After 20 minutes, the reaction mixture was concentrated under reduced pressure, and the resulting residue was purified by reverse phase chromatography eluting with 30-95% MeCN/H2O+0.1% TFA. Product fractions concentrated under reduced pressure to yield the title compound. 1H NMR (DMSO-d6) δ 8.53 (dd, J=4.4 Hz, J=1.6 Hz, 1H), 8.14 (dd, J=8.0 Hz, J=1.5 Hz, 1H), 8.04 (d, J=0.6 Hz, 1H), 7.89 (d, J=8.9 Hz, 1H), 7.79 (d, J=8.9 Hz, 1H), 7.44 (d, J=0.6 Hz, 1H), 7.21 (dd, J=8.0 Hz, J=4.5 Hz, 1H), 6.38 (d, 2H). HRMS (M+1)=470.0076
