Reaktionsschritte

To a scintillation vial containing 6-(5-chloro-2-fluoropyridin-4-yl)-N2-((tetrahydro-2H-pyran-4-yl)methyl)pyrazine-2,3-diamine (17 mg, 0.050 mmol) was added DMSO (1.3 ml) and trans-cyclohexane-1,4-diamine R2 (57.5 mg, 0.503 mmol). The homogenous reaction mixture was capped and heated to 100° C. in a oil bath for 16 hr. The reaction mixture was purified by reverse phase preparative HPLC to yield 6-(2-(trans-4-aminocyclohexylamino)-5-chloropyridin-4-yl)-N2-((tetrahydro-2H-pyran-4-yl)methyl)pyrazine-2,3-diamine (13.7 mg, 0.025 mmol, 49.9% yield), LCMS (m/z): 432.1 (MH+), retention time=0.41 min as a TFA salt after lypholyzing. 1H NMR (400 MHz, METHANOL-d4) d ppm 1.30-1.50 (m, 4H) 1.51-1.65 (m, 2H) 1.69-1.78 (m, 2H) 1.93-2.06 (m, 1H) 2.07-2.24 (m, 4H) 3.10-3.19 (m, 1H) 3.36-3.45 (m, 2H) 3.48 (d, J=6.65 Hz, 2H) 3.64-3.75 (m, 1H) 3.96 (dd, J=11.35, 3.13 Hz, 2H) 7.04-7.10 (m, 1H) 7.64 (s, 1H) 8.01 (s, 1H).
