실험 절차
A mixture of 234 mg (0.54 mmol) of 3-(1-benzyl-1H-pyrazol-4-yl)-5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine, 3.0 ml (32 mmol) of 1,4-cyclohexadiene and 400 mg of 20% palladium hydroxide on carbon was heated to reflux for 8 hours. The mixture was filtered, the filtrate concentrated in vacuum to afford 106 mg (31%) of 3-(1H-Pyrazol-4-yl)-5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine over three steps. ESI MS m/z 347.1 (M+1).
