Reaction Steps
A mixture of trans-N1-(5-chloro-4-iodopyridin-2-yl)cyclohexane-1,4-diamine (from step 1 above, 300 mg, 0.853 mmol), 2-fluoro-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (285 mg, 1.280 mmol), PdCl2(dppf).CH2Cl2 adduct (84 mg, 0.102 mmol), DME (4 ml), Ethanol (1 ml), and 2M sodium carbonate (1.706 ml, 3.41 mmol) reaction mixture was stirred at about 90° C. until done by LCMS. The reaction mixture mixture was cooled, then diluted with 25 ml of ethyl acetate and 10 ml of methanol, filtered, and concentrated to yield a crude solid. The crude solid was dissolved in DMSO, filtered and purified by prep LC. After lyapholization, 200 mg of the title compound was obtained as a TFA salt. LCMS (m/z): 321.0 (MH+), retention time=0.48 min.
