The flask was charged with N-(3-bromomethylphenyl)-N-(ethylsulfonyl)pyrid-3-ylmethylamine (0.180 g, 0.500 mmol), 2-methoxyphenylboronic acid (0.113 g, 0.75 mmol), 4.5 ml of DME, 1.5 ml of 2 M Na2CO3, and terakis(triphenylphosphine) palladium(0) (0.018 g, 0.016 mmol). After N2-flushing, the mixture was heated at 50° C. overnight. The reaction mixture was concentrated, diluted with water, and extracted with EtOAc. The organic layer was washed with brine and concentrated. The residue was chromatographed on a silica-gel column with 1:1 to 1:3 toluene/EtOAc to afford the title compound. 1H NMR:, 8.37 (d,1H,J=3.9 Hz), 8.24 (s,1H), 7.55 (d,1H,J=7.8 Hz), 6.74-7.17 (m,9H), 4.76 (s,2H), 3.80 (s,2H), 3.69 (s,2H), 2.94 (q,2H,J=7.3 Hz), 1.32 (t,3H,J=7.3 Hz). MS calcd. 396.2; MS (M+1) 397.2.
