4-Amino-N-{2-[4-(4-fluorobenzoyl)piperidino]ethyl}-N-(3-methoxyphenyl)benzamide (475.0 mg, 1.00 mmol) was dissolved in methanol (4.0 ml) and mixed with a methanol solution (3.0 ml) of fumaric acid (58.0 mg, 0.50 mmol) at 0° C. Thereafter, the thus precipitated crystals were collected by filtration and recrystallized from an ethanol-water mixture solution to obtain 481.0 mg (90.0%) of the title compound in a colorless powder form.
