A mixture of N-(2-(5-bromopyridin-3-yl)propan-2-yl)ethanesulfonamide (30 mg, 0.098 mmol), 2-chloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (27.0 mg, 0.103 mmol), PdCl2(dppf).CH2Cl2 adduct (1.994 mg, 2.441 μmol) and sodium carbonate (98 μl, 0.195 mmol) in DMF (10 mL) was heated to 100° C. overnight. After concentration, the residue was purified by column (MeOH—CH2Cl2, v/v, 10-20%) yielded the title compound as oil (1 mg). ESI-MS m/z: [M+1]+ 364.0, Retention time=1.40 min. 1H NMR (400 MHz, CDCl3): δ 1.31 (t, J=7.37 Hz, 3H), 1.76 (s, 6H), 2.86-2.91 (m, 2H), 4.54 (brs, 1H), 7.52 (dd, J=1.7, 8 Hz, 1H), 7.67 (d, J=1.6 Hz, 1H), 7.72 (d, J=8 Hz, 1H), 7.95 (t, J=2.2 Hz, 1H), 8.67 (d, J=2.2 Hz, 1H), 8.76 (d, J=2.2 Hz, 1H).
