2-Biphenylcarboxylic acid Usage And Synthesis
Chemical Properties2-Biphenylcarboxylic acid is White powder
Uses2-Biphenylcarboxylic acid is used in the preparation of neuropeptide FF receptor antagonists. In addition it is used in the synthesis of disubstituted piperidines as orexin receptor antagonists.
UsesIt is used as a pharmaceutical intermediate. he reaction of 2?-substituted biphenyl-2-carboxylic acids (where the 2?-substituent is H, CO2H, NO2, Cl, OMe, or CO2Me) with lead tetra-acetate in refluxing benzene solution, under a nitrogen atmosphere, affords 3,4-benzocoumarin as a major organic product.
