Procedure

General procedure E was followed using 1-(3,5-dichloropyridin-4-yl)piperidine-4-carboxamide 23 (75 mg, 0.27 mmol), 2-methoxypyrimidine-5-boronic acid (53 mg, 0.34 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, 96:4-82:18, biotage 25+S) to furnish the title compound as an off white solid (20 mg, 21%), along with recovered 1-(3,5-dichloropyridin-4-yl)piperidine-4-carboxamide as a white solid (32 mg, 43% RSM), LC-MS (ESI, 4 min) Rt 1.76 min, m/z 348 (100%, [M+H]+); m/z (ESI) C16H18N5O2Cl requires 347.1149, found [M+H]+ 347.1147.
