Versuchsvorschrift

A 350 ml heavy-walled vessel was charged with (1H-benzo[d]imidazol-2-yl)(4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanone (1.2 g, 3.02 mmol) and ammonium formate (5.71 g, 91 mmol) in THF (20 mL) and MeOH (20.00 mL). The reaction was evacuated 2× and treated with palladium on carbon 10% (0.321 g, 0.302 mmol) under nitrogen. The vessel was capped and the mixture was heated to 70° C. After 6 hours, the reaction was allowed to cool down to RT and filtered through celite. The filtrate was reduced under vacuum and the resulting residue was partition with DCM and water. The DCM layer was washed (2×) with an aqueous saturated solution of sodium bicarbonate, then with water and then brine. The organic layer was then dried with sodium sulfate and purified by column chromatography on silica gel using a gradient of 2 to 12% MeOH in DCM to give (1H-benzo[d]imidazol-2-yl)(4-(3-(tetrahydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)methanol as a white solid. MS (ESI, pos. ion) m/z: 401.9 (M+1).
