2,4-Dichloropyrimidine → 3-(2-Chloropyrimidin-4-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 2,4-dichloropyrimidine were reacted. The product was purified via silica gel chromatography using a gradient of ethyl acetate in heptane to afford 60 mg (50%) of 3-(2-Chloropyrimidin-4-yl)-5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridine. ESI MS m/z 439.2 (M+1).
