実験手順

A solution of (4-{[4-{[6-bromo-2-(methylcarbamoyl)pyridin-3-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)propylphosphinic acid (Compound 74B, 0.370 g, 0.599 mmol), 3-[4-(tributylstannanyl)-1H-1,2,3-triazol-1-yl]propan-1-ol (Compound 64B, 0.299 g, 0.719 mmol) and DIPEA (0.313 mL, 1.80 mmol) in 1,2-dichloroethane (10.0 mL) was charged with (benzotriazol-1-yloxy)tripyrrolidino-phosphonium hexafluorophosphate (0.936 g, 1.80 mmol). The resulting mixture was stirred at rt for 16 hours. The reaction mixture was quenched with sat. aq. NaHCO3 (10 mL) and extracted with DCM (20 mL). The organic layer was washed with sat. aq. 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→90:10) as eluent. The fractions containing product were combined and concentrated under reduced pressure to yield an off-white solid (352.1 mg, 57.8%). MS (ESI): m/z 1016.90 [M+H]+. UPLC: tR=1.44 min (UPLC-SQD: analytical_non-polar 2 min).
