Reaction Steps

To a solution of 2-bromo-6-(tributylstannyl)pyridine (2.0 g, 4.47 mmol) in Et3N (3.12 mL, 22.37 mmol) and was added 1-methyl piperazine (2 ml, 17.89 mmol). The reaction was heated at 100° C. for 24 h then cooled to RT, diluted with water, and extracted with EtOAc. The combined organic layer were washed with brine, dried and concentrated. The residue was purified with silica gel chromatography to give 1-methyl-4-(6-(tributylstannyl)pyridin-2-yl)piperazine (1.4 g, 70.3%). MS (ESI, pos. ion) m/z: 466.2 (M+1); 1H-NMR (CDCl3, 300 MHz) δ 7.3 (1H, t), 6.8 (1H, d), 6.5 (1H, d), 3.6 (4H, t), 2.5 (4H, t), 2.4 (3H, s), 1.5-1.7 (6H, m), 1.2-1.5 (6H, m), 1.0-1.2 (6H, q), 0.8-0.9 (9H, q).
