Reaction Steps

A mixture of 2-iodo-4-methyl-6-(methylthio)-1,3,5-triazine (100 mg, 0.374 mmol), 2-fluoro-3-(tributylstannyl)pyrazine (145 mg, 0.374 mmol) and tetrakis(triphenylphosphine)palladium(0) (43.3 mg, 0.037 mmol) in toluene (2 mL) was stirred at 110° C. for 18 h. The mixture was cooled down to room temperature. The solvent was removed in vacuo and the residue was purified by silica gel chromatography eluting with 40% EtOAc/hexanes to give 2-(3-fluoropyrazin-2-yl)-4-methyl-6-(methylthio)-1,3,5-triazine (42 mg, 0.177 mmol, 47.3% yield). 1H NMR (300 MHz, CDCl3) δ 8.73 (s, 1H); 8.42 (s, 1H); 2.73 (s, 3H); 2.65 (s, 3H). m/z (ESI, +ve ion) 238.0 (M+H)+.
