1,4-Cyclohexadiene → 3-(6-Fluoropyridin-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-5-(tetrahydro-2H-pyran-3-yl)-1H-pyrazolo[3,4-c]pyridine

Participants

Reaction Steps

A mixture of 68 mg (0.18 mmol) of 5-(3,4-dihydro-2H-pyran-5-yl)-3-(6-fluoropyridin-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine, 2.0 ml (21 mmol) of 1,4-cyclohexadiene and 300 mg of 10% palladium on carbon in 8 ml of ethanol was heated to reflux for 24 hours. The mixture was filtered through celite, the filtrate concentrated in vacuum to afford 70 mg (100%) of 3-(6-Fluoropyridin-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-5-(tetrahydro-2H-pyran-3-yl)-1H-pyrazolo[3,4-c]pyridine. ESI MS m/z 383.1 (M+1).
