Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optically active piperidine derivative excellent in anti-histaminic activity and anti-allergic activity. SOLUTION: This benzene sulfonic acid salt of 4-[4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidino]butanoic acid expressed by formula (I) and having an (S) form of absolute configuration, and the method for producing the same are provided. Since the acid adduct salt has less moisture absorption and is excellent in physicochemical stability, it is especially suitable compound as a medicine. COPYRIGHT: (C)2007,JPO&INPIT
