Reaction Steps
A mixture of trans-4-(5-chloro-4-iodopyridin-2-yl-amino)cyclohexanol (575 mg, 1.631 mmol), 2-fluoro-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (655 mg, 2.94 mmol), PdCl2(dppf).CH2Cl2 adduct (133 mg, 0.163 mmol), DME (15 ml), and t 2M sodium carbonate (4.48 ml, 8.97 mmol) reaction mixture was stirred at 95° C. for 2 hr, followed by LCMS. The reaction mixture was cooled to room temperature, mixed with 20 ml of ethyl acetate, 15 ml of methanol, filtered and concentrated to yield a crude product. The crude was purified by silica gel chromatography using a 40 g column, eluting from 35%-85% ethyl acetate with hexane. The desired fractions were combined and concentrated to constant mass, giving 440 mg of titled compound as free base. LCMS (m/z): 322.2 (MH+), retention time=0.53 min.
