  • Patent number: 6348624
    Abstract: The subject invention involves processes for making 2,4-difluoro-3-Q1-benzoic acid, wherein Q1 is derived from an electrophilic reagent, comprising the steps of: (a) treating 1-bromo-2,4-difluorobenzene with a strong, non-nucleophilic base; then treating with an electrophilic reagent which provides Q1, or a functional moiety which is then transformed to Q1, producing 1-bromo-2,4-difluoro-3-Q1-benzene; (b) treating the 1-bromo-2,4-difluoro-3-Q1-benzene with an alkali or alkaline earth metal or organometallic reagent; then treating with carbon dioxide, or with a formylating agent followed by oxidation, to produce 2,4-difluoro-3-Q1-benzoic acid. The subject invention also involves optional additional steps to further modify Q1, or to substitute a non-hydrogen moiety at the 5-position, at the 6-position, or at both, of the phenyl ring of the 2,4-difluoro-3-Q1-benzoic acid.

  • Patent number: 6333431
    Abstract: An object of the present invention is to provide a commercially advantageous process for preparing a fluoro benzoic acid. The process according to the present invention comprises either alkylating a fluoro benzoic acid of the formula wherein R1 is halogen, or reducing a fluoro benzoic acid of the formula wherein R1 is as defined above and R2 is lower alkyl to thereby produce a fluoro benzoic acid represented by the formula wherein R1 and R2 are as defined above.

  • Patent number: 6303812
    Abstract: Disclosed is a method of isolating the aromatic product formed when a substrate having the general formula is dehalogenated, forming a product mixture of copper salts and aromatic product, where X is the halogen removed from the substrate to form the aromatic product, R′ is COOH, COOR, COR, CN, COH(R)2, or SO3H, each R″ is independently selected from halogen, R, or OR or two vicinal R″ groups form one or more fused aromatic rings, R is alkyl from C1 to C18 or aryl from C6 to C18, and n is 1 to 4. Water in an amount about 1 to about 5 times the amount of the substrate is added to the product mixture, forming an organic phase that contains the aromatic product and an aqueous phase that contains the copper salts. If the density of the organic phase differs from the density of said aqueous phase by less than 0.1 g/cc, a suitable solvent is added to the product mixture in an amount sufficient to increase the differences between the organic and aqueous phases to at least 0.
