Versuchsvorschrift

Methyl 3-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-5-methylbenzoate (3.49 g, 7.28 mmol) was dissolved in tetrahydrofuran (THF) (90 ml) and water (30.0 ml) was added. Lithium hydroxide (0.458 g, 10.92 mmol) was added and the mixture stirred under argon at room temperature overnight. The THF was rotavaped off, and the aqueous residue was adjusted to ˜pH of 6 with 1N HCL. A white solid formed and was filtered and washed 2× with water (10 mL). This solid was dried at 50° C. in a vacuum oven for 6 h to give the title compound as a white solid. LC-MS m/z 466.0 (M+H)+, 0.73 min (ret time); mp 236-239° C.; analytical HPLC shows 97.3% purity, (ret time 10.841 min).
