我给你这一段文字，你从上下文，分析一下，因为你的翻译我还是不太理解。谢谢

Preparation of 1-(N2)2: Method 2. A 50 mL round-bottomed flask
was charged with 0.102 g (0.15 mmol) of 1-Br2 and approximately 30
mL of diethyl ether. The resulting blue suspension was cooled to -35
°C in the drybox freezer. Via microsyringe, 0.293 mL (0.293 mmol)
of a 1.0 M solution of NaBEt3H in toluene was added to the reaction
flask. After being stirred under a N2 atmosphere at ambient temperature
for 3 h, the green-purple solution was filtered through Celite, and the
volatiles were removed from the filtrate in vacuo. Recrystallization of
the resulting residue from pentane at -35 °C afforded analytically and
spectroscopically pure 1-(N2)2.
