Versuchsvorschrift

Palladium on charcoal (10%, 50% w/w water, 8 g) was treated with ethanol (200 mL) followed by a solution of 5-(azidomethyl)-1,6-diethyl-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[3,4-b]pyridin-4-amine (39.94 g, 121 mmol) in ethanol (1,200 mL). The mixture was stirred under an atmosphere of hydrogen for 16 h. The catalyst was then removed by filtration and the filtrate removed of solvent in vacuo to reveal 41.24 g of a black oil. The product was purified by flash chomatography on 1 kg of silica using a step gradient from 5-20% methanol in dichloromethane to afford 32.66 g of the title compound. LC-MS m/z 304 (M+H)+, 1.71 min (ret time).
