Procedure

N-(3′-Fluoro-6′-methyl-2,2′-bipyridin-4-yl)-2-(4-methoxybenzyl)-2H-pyrazolo[4,3-b]pyridin-7-amine (120 mg, 0.272 mmol) was dissolved in TFA (5 mL) and heated at 70° C. for 3 hours. The reaction mixture was then cooled and evaporated under vacuum to give a residue which was triturated with ether to give the title compound as a TFA salt (80 mg, 92% yield). MS [M+H] found 321.3.
