Participants

Reaction Steps

General procedure E was followed using 1-(3,5-dichloropyridin-4-yl)piperidine-4-carboxamide 23 (75 mg, 0.27 mmol), 1,3,5-trimethyl-1H-pyrazole-4-boronic pinacol ester (65 mg, 0.27 mmol), tetrakis(triphenylphosphine)palladium(0) (16 mg, 5 mol %), acetonitrile (3 mL) and 0.5 M sodium carbonate (0.77 mL, 0.38 mmol). The crude product was purified by flash column chromatography on silica gel (CH2Cl2, EtOH, 94:6-80:20, biotage 25+S) to furnish the title compound as a very pale yellow solid (34 mg, 35%), along with recovered 1-(3,5-dichloropyridin-4-yl)piperidine-4-carboxamide (52 mg, 57% RSM), LC-MS (ESI, 4 min) Rt 1.55 min, m/z 348 (100%, [M+H]+); m/z (ESI) C17H22N5OCl requires 347.1513, found [M+H]+ 347.1508.
