Reaction Steps
A mixture of trans-N1-(4-bromopyridin-2-yl)cyclohexane-1,4-diamine (102 mg, 0.377 mmol), 2-fluoro-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (80 mg, 0.359 mmol), PdCl2(dppf).CH2Cl2 adduct (29.3 mg, 0.036 mmol), DME (2 ml), Ethanol (0.2 ml), and 2M sodium carbonate (0.717 ml, 1.435 mmol) reaction mixture was stirred at about 85° C. until completion, as indicated by LCMS. The crude mixture was cooled to room temperature, diluted with 5 ml of ethyl acetate and 2 ml of methanol, filtered and concentrated to yield a crude solid. The solid was dissolved in DMSO, refiltered, purified by prep LC, and lyophilized to yield 64 mg of the title compound as its TFA salt. LCMS (m/z): 287.2 (MH+), retention time=0.43 min.
