6-(5-chloro-2-fluoropyridin-4-yl)-3-ethyl-N-((tetrahydro-2H-pyran-4-yl)methyl)pyrazine-2-amine (0.0053 g, 0.015 mmol) was dissolved in DMSO (1 ml). This was treated with 1,4-diaminocyclohexane (0.017 g, 0.151 mmol). The reaction mixture was then heated at 100° C. for 4 hr. Additional 1,4-diaminocyclohexane (0.017 g, 0.151 mmol) and triethylamine (0.0084 ml, 0.012 g, 0.060 mmol) were added. Heating at 100° C. was continued for 17 hr. The reaction mixture was purified using prep HPLC. The material was purified by preparative reverse-phase HPLC to give 0.0040 g of trans-N1-(5-chloro-4-(5-ethyl-6-((tetrahydro-2H-pyran-4-yl)methyl)aminopyrazin-2-yl)pyridin-2-yl)cyclohexane-1,4-diamine as the TFA salt. LCMS (m/z): 445.2 (MH+), retention time=0.54 min.
