Vorschrift

400 mg (0.68 mmol) of 3-[4,6-dichloro-5-(8-oxa-3-azabicyclo[3.2.1]oct-3-yl)-2-pyrimidinyl]-1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine (example XII, step 7) are dissolved in 200 ml of methanol, and 86 mg of ammonium formate are added. Under argon, 26 mg of palladium on activated carbon (10%) are added, and the mixture is heated under reflux for 3 days. The reaction mixture is filtered and the residues are washed with methanol. The solvent is removed in vacuo, and the residue is purified by preparative HPLC. 99 mg (35% of theory) of the product are obtained.
