Reaction Steps

Production Example 3 was repeated except that 1-(4-methoxyphenyl)piperazine dihydrochloride and isovaleryl chloride were replaced with 1-(2,5-difluoro-4-methoxyphenyl)-piperazine (228 mg) and 4-tert-butylbenzoyl chloride (234 μL), respectively, to provide crude 1-(4-tert-butylbenzoyl)-4-(2,5-difluoro-4-methoxyphenyl)piperazine (433 mg).
