Reaktionsschritte

To a solution of 3-amino-6-trifluoromethyl pyridine (0.25 g, 1.2 mmol, 2.0 equiv) and 2-bromopyridyl-5-boronic acid (0.10 g, 0.62 mmol, 1.0 equiv) in 5 Ml dichloromethane was added pyridine (0.10 Ml, 1.2 mmol, 2.0 equiv), copper (II) acetate (0.17 g, 0.93 mmol, 1.5 equiv) and 4 Å molecular sieves. The heterogeneous reaction mixture was allowed to stir vigorously open to air overnight. The reaction was then filtered through Celite, concentrated in vacuo, and purified by silica gel chromatography to afford the title compound: (M+H)+319.9.
