Vorschrift

To a round bottomed flask was added N-(4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)-1H-benzo[d]imidazol-2-amine (0.0784 g, 0.204 mmol), palladium, 10% wt. on activated carbon (0.043 g, 0.041 mmol), and acetic acid (0.023 mL, 0.408 mmol) in THF (a few drops of MeOH was added to help solubility). To remove oxygen from the round bottomed flask, the flask was flushed by nitrogen and the placed under vacuum repeatedly. Hydrogen gas was then introduced to the reaction and allowed to stir. Upon completion, the reaction was filtered through celite. The crude product was run through a SCX cartridge. Impurities were removed from column using DCM and MeOH. The product was flushed from the cartridge using 2.0 ammonia in MeOH to provide N-(4-(3-(Tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)-1H-benzo[d]imidazol-2-amine. MS (ESI, pos. ion) m/z: 387.0 (M+1). IC50 (uM) +++++.
