実験手順

Following the same procedure as described in Example 1, (2-bromo-6-methyl-pyridin-3-yl)amine (200 mg, 1.07 mmol) reacted with (PPh3)2PdCl2 (37 mg, 0.05 mmol), Cul (10 mg, 0.05 mmol) and 1-ethynyl-3-methoxy-benzene (204 μl, 1.60 mmol) in triethylamine (5 ml) during 1.5 h. The crude residue was purified by flash chromatography (hexane/ethyl acetate 4:1) to yield 118 mg (0.50 mmol, 46%) of (2-(3-methoxy-phenylethynyl)-6-methyl-pyridin-3-yl)amine as a yellow brown solid.
