A suspension of (4-{[4-{[6-bromo-2-(methylcarbamoyl)pyridin-3-yl]amino}-5-(trifluoromethyl)pyrimidin-2-yl]amino}-3-methoxybenzyl)propan-2-ylphosphinic acid (Compound 68B, 0.240 g, 0.389 mmol) and 3-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]propan-1-ol (Compound 3E, 97.9 g, 0.388 mmol) in 1,2-dichloroethane (8.53 mL) and DIPEA (0.812 mL, 4.66 mmol) was charged with (benzotriazol-1-yloxy)tripyrrolidino-phosphonium hexafluorophosphate (1.21 g, 2.33 mmol). The reaction mixture was stirred 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→90:10) as eluent to afford the title compound as an off-white foam. MS (ESI): m/z 851.84/853.82 [M+H]+. UPLC: tR=1.57 min (UPLC-SQD: analytical—2 min).
