Reaction Steps

2-[1,2-Dibromo-2-(3-fluorophenyl)ethyl]-6-methylpyrazine (2.97 g, 7.94 mmol) was dissolved in THF (40 mL), treated with DBU (8.7 mL, 63 mmol), and heated to reflux. After 16 h the reaction mixture was cooled, filtered, concentrated in vacuo, and purified by column chromatography eluting with 80:20 then 75:25 hexane:ethyl acetate to afford 2-[(3-fluorophenyl)ethynyl]-6-methylpyrazine (427 mg, 25% yield). This material was carried on to the salt formation without further purification.
