2,6-Dibromopyridine → 3-(6-Bromopyridin-2-yl)-5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridine

Reaction Steps

Following the Stille coupling procedure of Example 299, 5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-3-(trimethylstannyl)-1H-pyrazolo[3,4-c]pyridine and 2,6-dibromopyridine were reacted. The mixture was purified via silica gel chromatography using a gradient of ethyl acetate in heptane to afford 81 mg (67%) of 3-(6-Bromopyridin-2-yl)-5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridine. ESI MS m/z 482.2 (M+1).
