Versuchsvorschrift

Combined 6-(4-bromo-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide (25 mg, 0.063 mmol), (4-cyano-2-methylphenyl)boronic acid (30.5 mg, 0.190 mmol), sodium carbonate (26.6 mg, 0.316 mmol), and PdCl2(dppf)-CH2Cl2 adduct (2.58 mg, 3.16 μmol) in dioxane (0.2 mL) and water (0.05 mL) and purged with nitrogen. The reaction mixture was heated in a microwave on high absorbance for 1 hour at 110° C., cooled to 23° C. and diluted with water (1 mL) to give a residue. The residue was extracted with EtOAc (2×1 mL), the organic layers were combined, washed with brine (0.5 mL), dried over Na2SO4, filtered through a Hydrophilic PTFE 0.45 um filter (Millipore Millex™-LCR), rinsed with EtOAc, and dried in vacuo to provide 6-(4-(4-cyano-2-methylphenyl)-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide (27.3 mg, 100% yield) as a brown oil. MS m/z [M+H]+ 432.5.
