Reaction Steps

(S)-2-bromo-N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)thiazole-4-carboxamide (300 mg, 0.666 mmol), 1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazole-5-boronic acid pinacol ester (222 mg, 0.799 mmol), tetrakis(triphenylphosphine)palladium (23 mg, 0.020 mmol), THF and 2M Na2CO3 solution were added in a microwave flask and heated in microwave at 120° C. for 2 h. 1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazole-5-boronic acid pinacol ester (37 mg) and tetrakis(triphenylphosphine)palladium (8 mg) were added and the reaction mixture was heated in 120° C. for 1 h. The reaction mixture was diluted with DCM and washed twice with Na2CO3 solution. Organic phase was dried and evaporated to dryness. The product was purified by Flash-chromatography. Yield 3.7%. m/z [522.0+1].
