Reaction Steps

Potassium carbonate (0.418 mL, 0.836 mmol), Pd(OAc)2 (2.82 mg, 0.013 mmol) was added to a stirred, room temperature mixture of 4-bromo-1-methyl-1H-pyrazole-3-carbaldehyde (79 mg, 0.418 mmol) and (2,3,4-trifluorophenyl)boronic acid (96 mg, 0.543 mmol) in EtOH (0.7 mL) and the mixture was stirred at 90° C. for 24 hours. The mixture was cooled, aqueous sodium hydrogen carbonate (saturated, 10 mL) was added and the mixture was extracted with ethyl acetate (2×15 mL). The combined organic fractions were washed with water, dried (MgSO4) and filtered. The solvent was evaporated under reduced pressure to give the crude intermediate which was used in the next step.
