Reaction Steps
Combined 4-(1-(5-bromo-4-methylpyridin-2-yl)-5-((2-(trimethylsilyl)ethoxy)methoxy)-1H-pyrazol-4-yl)benzonitrile (10.0 g, 20.66 mmol), DMF (60 mL) and MeOH (60 mL) then added triethylamine (6.26 g, 61.98 mmol) and Pd(dppf)Cl2 (756.2 mg, 1.033 mmol). The mixture was stirred at 120° C. under 1 MPa of CO overnight. Then the reaction mixture was evaporated in vacuum to give a residue which was combined with water, filtered, and the aqueous was extracted with EtOAc (100 mL×2). The combined EtOAc layers were washed with brine and dried (Na2SO4), and concentrated to give the title compound (8.67 g).
