A PROCESS FOR THE SYNTHESIS OF ALKOXYALKYL (TRIFLUOROMETHYLPHENYL) METHANONES

摘要

A new process is described for the preparation of (alkoxyalkyl) (4-trifluoromethylphenyl) methanones. The process comprises reacting a 4-trifluoromethylbenzonitrile with an alkoxyalkyl Grignard in the presence of a suitable polar aprotic solvent. The compound (4-methoxybutyl) (4-trifluoromethylphenyl) methanone is useful as an intermediate in the preparation of the antidepressant drug fluvoxamine.
