実験手順

A suspension of (4-{[4-{[6-bromo-2-(methylcarbamoyl)pyridin-3-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)propylphosphinic acid (Compound 74B, 0.500 g, 0.810 mmol) and 2,2-dimethyl-3-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]propan-1-ol (Compound 47B, 227 mg, 0.809 mmol) in 1,2-dichloroethane (24.4 mL) and 1-methylimidazole (0.967 mL, 12.1 mmol) was charged with (benzotriazol-1-yloxy)tripyrrolidino-phosphonium hexafluorophosphate (2530 mg, 4.85 mmol). After stirring at 60° C. for 16 hours, the reaction mixture was quenched with water (10 mL) and extracted with DCM (20 mL). The organic layer was washed with NaHCO3 (10 mL), washed with brine (15 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure to a brown oil. The crude material was purified using a Teledyne ISCO Combiflash® Rf system using 1:1 DCM-EtOAc/MeOH (100:0→95:5) as eluent. The fractions containing product were combined and concentrated under reduced pressure to yield an off-white foam (318.1 mg, 45%). MS (ESI): m/z 879.93/881.94 [M+H]+. UPLC: tR=1.67 min (UPLC-TOF: polar—2 min).
