合成路线 1（1. 合成：174508-31-7）
产率：83%
合成条件：With N-Bromosuccinimide; acetic acid In tetrahydrofuran at 20℃; for 2 h;
实验步骤：将3,4-乙二氧基二氧噻吩（1.42g，10.60mmol），N-溴代琥珀酰亚胺（3.74g，12.80mmol）和乙酸（20mL）的THF（20mL）溶液依次加入圆底清漆中。 将混合物在室温下搅拌2小时。 反应后，将反应混合物倒入蒸馏水中并用玻璃棒搅拌，过滤沉淀物，得到A4，为白色固体（2.50g，8.30mmol，收率83％）。 1 H NMR（400MHz，CDCl 3，ppm）：δ= 4.27（s，4H）。
