Reaction Steps

4-Chloro-6-[(2S)-2,4-dimethyl-1-piperazinyl]-5-fluoro-2-methylpyrimidine (0.277 g, 1.07 mmol), hydrazine monohydrate (0.5 mL) and DMSO (2.0 mL) were stirred at room temperature overnight. Then the reaction was heated to 50° C. and stirred for 7 hours. Purified by RP-HPLC to provide 4-[(2S)-2,4-dimethyl-1-piperazinyl]-5-fluoro-6-hydrazino-2-methylpyrimidine as an orange solid (0.118 g, 43%). LCMS: (M+H)+=255.3.
