    摘要: The present invention relates to a novel method of synthesizing bepotastine or its benzenesulfonic acid salt and novel intermediates used therein. The present invention uses L-α-hydroxy acid for chiral resolution to form an L-α-hydroxy acid salt of a compound represented by the following formula (VII-1), so as to synthesize bepotastine or its benzenesulfonic acid salt in high optical purity.
