General procedure D (See Example 4) was followed using 1-(3,5-dichloropyridin-4-yl)piperidine-4-carboxamide 23 (24 mg, 0.088 mmol), benzene boronic acid (13 mg, 0.11 mmol), tetrakis(triphenylphosphine)palladium(0) (5 mg, 5 mol %), acetonitrile (1 mL) and 0.5 M sodium carbonate (0.25 mL, 0.12 mmol) for 30 min. The crude product was purified by preparative hplc (H2O, MeCN, gradient 90:10 to 10:90 over 30 min) to furnish the title compound as a white solid (6 mg, 22%), LC-MS (ESI) Rt 1.63 min, m/z 316 (100%, [M+H]+); m/z (ESI) C17H18ClN3NaO requires 338.1031 found [M+Na]+ 338.1030.
