Reaction Steps

A mixture of 3-(6-bromo-2-pyridyl)-1H-pyrazolo[5,4-b]pyridine (50 mg,), potassium carbonate (150.6 mg, 1.09 mmol) and 2-methylpropane-1,2-diamine (40.1 mg, 0.45 mmol) in DMF (0.7 mL) was heated at 150° C. for 24 hours. The mixture was allowed to cool, filtered and the resultant filtrate purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 uM, 100 A column, gradient 10%-95% B (solvent A: 0.05% TFA in water, solvent B: CH3CN) over 16 minutes at 25 mL/min]. The fractions were collected, passed through a sodium bicarbonate cartridge and freeze-dried to give the title compound as a white solid (33.5 mg, 36% Yield).
