Reaction Steps

Sodium hydride (100, %%, 0.06 mol) was added to a suspension of triazole (0.06 mol) in dimethyl formamide (100 ml) and the solution stirred at 20° until effervescence ceased. 2,2,7,7-Tetramethyl-4,5,dibromo-octan-3,6-dione (0.03 mol) was added portionwise at 20° to the stirred solution. After refluxing for 2 hours, the solution was cooled and poured into water to give a crystalline solid. Recrystallization from petroleum ether (60°-80°) gave the title compound as a white crystalline solid, m.p. 107°-8°.
