A mixture of the title compound, 1-(2-ethyl-1-methyl-1H-benzimidazol-6-yl)-4-((5-fluoro-3-thienyl)methoxy)pyridin-2(1H)-one and 1-(2-ethyl-1-methyl-1H-benzimidazol-6-yl)-4-((2-fluoro-3-thienyl)methoxy)pyridin-2(1H)-one obtained in step B in example 231 was subjected to HPLC separation (C18, mobile phase: H2O/CH3CN (0.1% TFA included)). The desired fraction was neutralized with saturated NaHCO3 solution and extracted with EtOAc. The organic layer was separated, dried over MgSO4 and concentrated in vacuo to give the title compound (26.8 mg) as a white solid.
