FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing a salt of tetrazole methanesulphonic acid of formula (I) 
, which involves acylating a compound (II) 
with a compound (III) 
and then adding methanesulphonic acid. The invention also relates to an intermediate compound of formula (II) and a method for production thereof.
EFFECT: method according to the present invention can cut reaction time, improve safety and enables to obtain salts of tetrazole methanesulphonic acid of high purity with high output without using a column chromatography technique.
