To a scintillation vial containing 3-chloro-6-(5-chloro-2-fluoropyridin-4-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)pyrazin-2-amine (20 mg, 0.056 mmol) was added DMSO (1 ml) and trans-4-aminocyclohexanol (32.2 mg, 0.280 mmol). The reaction mixture was capped and heated to 120° C. in an oil bath for 3 hr. The reaction product was purified by reverse phase preparative HPLC to yield trans-4-(5-chloro-4-(5-chloro-6-((tetrahydro-2H-pyran-4-yl)methyl)aminopyrazin-2-yl)pyridin-2-yl-amino)cyclohexanol (2.2 mg, 4.86 μmol, 8.69% yield), LCMS (m/z): 452.1 (MH+), retention time=0.76 min as a TFA salt after lypholyzing. 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.17-1.26 (m, 4H) 1.27-1.39 (m, 2H) 1.58 (dd, J=13.11, 1.76 Hz, 2H) 1.84-2.02 (m, 5H) 3.30 (d, J=7.04 Hz, 4H) 3.43-3.61 (m, 2H) 3.84 (dd, J=11.35, 3.13 Hz, 2H) 6.58 (s, 1H) 7.66 (s, 1H) 7.90 (s, 1H).
