Reaction Steps
A mixture of 4-methylsulfanyl-6-tributylstannanyl-pyrimidine (4) (1.80 g, 4.33 mmol), 2,3-dichloro-pyrazine (1.94 g, 13 mmol), PPh3 (0.907 g, 3.46 mmol) and palladium (II) acetate (194 mg, 0.866 mmol) in dioxane (15 mL) is degassed and sealed in a pressure tube. After stirring at 120° C. for 16 h, the reaction mixture is evaporated and purified by silica gel flash chromatography eluting with ethyl acetate in hexanes from 10% to 30% to afford the desired product 4-(3-chloro-pyrazin-2-yl)-6-methylsulfanyl-pyrimidine (37).
