Reaction Steps

A mixture of N-[2-(1,1-difluoroethyl)-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-benzimidazol-5-yl]acetamide (1.07 g, 3.17 mmol), 6 M aqueous solution of NaOH (5 mL) and MeOH (5 mL) was heated to 70° C. for 24 h. The reaction mixture was diluted with water (200 mL) and the product was extracted with EtOAc (4×100 mL). The combined organic layers were dried over anhydrous Na2SO4 and the solvent was concentrated to provide the title compound as white solid. Yield: 0.90 g (96%); MS (ESI) (M+H)+=296.2.
