実験手順
Production Example 9 was repeated except that 5-bromo-2-methoxytoluene was replaced with 4-bromo-2,5-difluoroanisole (446 mg), and 1-phenethylpiperazine was replaced with 4-benzylpiperidine (2.30 mL). The resulting crude product was purified on silica gel column chromatography (eluent, hexane: ethyl acetate=4:1) to provide 4-benzyl-1-(2,5-difluoro-4-methoxyphenyl)piperidine (304 mg).
後処理
- customThe resulting crude product was purified on silica gel column chromatography (eluent, hexane: ethyl acetate=4:1)
