実験手順

A solution of 3-amino-6-bromo-N-(4-((1R,3S)-3-(1,3-dioxoisoindolin-2-yl)cyclohexyl)pyridin-3-yl)-5-fluoropicolinamide (1.0 equiv), 3-fluoropyridin-4-yl-boronic acid (3.0 equiv.), tetrakistriphenylphosphine (0.2 equiv.) and triethylamine (3.0 equiv.) in 1:1 EtOH/toluene (0.1 M) was heated at 120° C. with microwave irradiation for 1200 seconds. Upon cooling, removal of the volatiles in vacuo, the Suzuki product was directly purified by reverse phase HPLC. The product fraction was lyophilized and the resulting phthalimide group was deprotected as described in Method 9 yielding, after RP HPLC purification and lyophilization, 5-amino-N-(4-((1R,3S)-3-aminocyclohexyl)-pyridin-3-yl)-3,3′-difluoro-2,4′-bipyridine-6-carboxamide as the TFA salt. LCMS (m/z): 425.1 (MH+); LC Rt=2.08 min.
