Example 35 Preparation of 5-((1R,2S)-2-aminocyclohexylamino)-3-(tetrahydro-2H-pyran-4-ylamino)pyrazine-2-carboxamide The title compound was prepared according to the synthetic scheme illustrated below: To the solution of 3,5-dichloropyrazine-2-carbonitrile (2.00 g, 11.5 mmol) in 30 mL NMP were added tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (2.71 g, 12.6 mmol) and DIEA (4.07 mL, 13.8 mmol). The mixture was stirred at RT for 1.5 h. To it was poured 300 mL water. After stirring vigorously for 2 h, the solid was isolated by filtration, washed with water and dried in vacuum oven for overnight to afford tert-butyl (1S,2R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)cyclohexylcarbamate in quantitative yield.
