General description
3-Fluorophthalic anhydride undergoes reduction with NaBH4 to afford 4-fluorophthalide and 7-fluorophthalide. It can be synthesized starting from 3-nitrophthaloyl dichloride.
Application
3-Fluorophthalic anhydride may be used in the preparation of substituted benzamides with potential neuroleptic activity. It may be employed as starting reagent for the synthesis of 8-fluoro-10-methyl-1,2-benzanthracene.
