摘要：
According to the present invention, a method for preparing tetrazole methanesulfonic acid salts comprises an acylation reaction using a novel 4-iodine-4H-chromene-2-carbothionic acid S-benzothiazole-2-yl ester. The method of the present invention can shorten a reaction time and improve safety as compared to conventional methods, and can prepare high-purity tetrazole methanesulfonic acid salts at a high yield rate without using a column chromatography method.
