To a solution of fumaric acid (58 mg) in ethanol (2 mL) was added a solution of 1-{4-fluoro-5-(2-fluoropyridin-3-yl)-1-[(4-methylpyridin-2-yl)sulfonyl]-1H-pyrrol-3-yl}-N-methylmethanamine (189 mg) in ethyl acetate (2 mL), and the mixture was concentrated under reduced pressure. The residue was recrystallized from ethanol to give the title compound as a white solid (yield 224 mg, 91%).
