Abstract: A process for manufacturing 2-isobutyl-6-(3-(methylamino)azetidin-1-yl)pyrimidin-4-amine of Formula (I): including starting from 6-chloro-2-isobutylpyrimidin-4-amine and tert-butyl azetidin-3-yl(methyl)carbamate, or another N-protected N-methylazetidin-3-amine, and performing the following steps: (a) coupling reaction of both compounds in dimethylsulfoxide in presence of potassium carbonate to afford an intermediate protected compound; and (b) deprotection of the protected compound to afford 2-isobutyl-6-(3-(methylamino)azetidin-1-yl)pyrimidin-4-amine. Also, a process for manufacturing the intermediate protected compound, wherein deprotection step (b) is omitted, and the compounds obtained from the processes.
