Organic amine salt of aminobenzoic acid derivative, and method for producing same

摘要

The purpose of the invention is to provide a novel organic amine salt or quaternary ammonium salt of the 3-{[((2E)-2-{1-[5-(4-t-butylphenyl)-4-hydroxy-3-thienyl]ethylidene}hydrazino)carbonothioyl]amino} benzoic acid represented by the formula shown below. The organic amine salt or quaternary ammonium salt has excellent pharmacokinetic characteristics and stability, and possessed properties useful for a drug.
