FIELD: biotechnology.
SUBSTANCE: invention relates to an intermediate product of the following formula or its salt, where R1 is hydrogen, used in a method for the production of N-((1S,3S)-3-(methyl(7H-pyrrolo[2,3-d]pyrimidine-4-yl)amino)cyclobutyl)propane-1-sulfonamide.
EFFECT: effective method is developed for the production of N-((1S,3S)-3-(methyl(7H-pyrrolo[2,3-d]pyrimidine-4-yl)amino)cyclobutyl)propane-1-sulfonamide useful as an inhibitor of protein kinases, such as Janus kinase enzyme (JAK), using a new intermediate compound.
