Procedure

A suspension of 4-bromo-N-(3-(4-cyclopropyl-4H-1,2,4-triazol-3-yl)phenyl)picolinamide (120 mg, 0.31 mmol), 3-pyridine boronic acid (77 mg, 0.62 mmol), dppf(Pd)Cl2 (23 mg, 0.03 mmol), potassium carbonate (86 mg, 0.62 mmol) in degassed toluene (2 mL), degassed water (1 mL) and degassed ethanol (1 mL) was heated at 100° C. for 1 hour. The solvent was removed under reduced pressure and the residue purified by reverse-phase HPLC, to give N-(3-(4-cyclopropyl-4H-1,2,4-triazol-3-yl)phenyl)-3,4′-bipyridine-2′-carboxamide as a white powder (58 mg, 0.15 mmol, 48% yield). C22H18N6O. 383.1 (M+1). 1H NMR (DMSO) d 10.98 (s, 1H), 9.12 (d, J=1.6 Hz, 1H), 8.87 (d, J=4.8 Hz, 1H), 8.72 (dd, J=4.8, 1.2 Hz, 1H), 8.63 (s, 1H), 8.60 (s, 1H), 8.48 (d, J=1.2 Hz, 1H), 8.34 (m, 1H), 8.11 (m, 2H), 7.69 (d, J=8.0 Hz, 1H), 7.59 (m, 2H), 3.66 (m, 1H), 1.09 (m, 2H), 0.94 (m, 2H).
