Reaction Steps

A suspension of (E)-N-(6-(2-(piperidin-1-yl)ethoxy)-1-(piperidin-4-yl)-1H-imidazo[4,5-c]pyridin-2(3H)-ylidene)benzamide (0.089 g, 0.198 mmol) and potassium carbonate (0.082 g, 0.595 mmol) in DMF (2 mL) was cooled to 0° C. under nitrogen. To this mixture was added 1-bromo-2-methylpropane (0.054 g, 0.397 mmol). The ice bath was removed, and the resulting mixture was stirred for 16 hours at RT. The reaction mixture was diluted with water (10 mL) and DCM (30 mL), and the organic layer was collected, concentrated and purified by silica gel chromatography (5-30% MeOH/DCM) to afford (E)-N-(1-(1-isobutylpiperidin-4-yl)-6-(2-(piperidin-1-yl)ethoxy)-1H-imidazo[4,5-c]pyridin-2(3H)-ylidene)benzamide as an off-white solid (20 mg, 19.97% yield). MS m/z=505.2 [M+H]. Calc'd for C29H40N6O2: 504.3.
