  • Publication number: 20110201792
    Abstract: Methods are disclosed for preparing compounds of Formula I: where R1, R3, and R4 are independently hydrogen or C1 to C4 alkyl, and R2 is: where R5 is selected from the group consisting of hydrogen and C1 to C4 alkyl, or where R6, R7 and R8 are independently hydrogen or C1 to C4 alkyl; or the esters or pharmacologically acceptable salts thereof. The methods can involve converting a suitably functionalized aniline compound to a diazonium salt (which aniline compound can be first formed by reduction of a nitrobenzene) and coupling the diazonium salt with a suitably functionalized benzene compound. The suitably functionalized aniline compound either includes a primary alcohol or aldehyde group, which is then oxidized to a carboxylic acid group, or includes a nitrile or amide group, which is hydrolyzed to a carboxylic acid group. The methods can also involve the direct coupling (via reduction of nitro groups to form an azo linkage) of suitably functionalized nitrobenzenes.
