Participants

Reaction Steps

3-(5-Bromo-pyridin-2-yl)-1,1-dimethyl-prop-2-ynylamine (1.05 g, 4.4 mmol), 2-methylthio-4-tri-butylstannylpyrimidine (1.83 g, 4.4 mmol) and PdCl2(PPh3)2 (154 mg, 0.22 mmol) in toluene (22 ml) were refluxed under argon for 2 hours. A second portion of 2-methylthio-4-tri-n-butylstannylpyrimidine (1.83 g, 4.4 mmol) was added and the mixture refluxed for 1 hour. The reaction mixture was filtered, evaporated and purified via chromatography on silicagel (TBME/MeOH/ammonia:97/2.7/0.3 to 95/4.5/0.5) to give the title compound as orange-brown solid, which was recrystallized form ether/hexanes. Yield: 500 mg (40%).
