合成路线 1（1. 合成：37500-95-1）
产率：75%
合成条件：With aluminum (III) chloride In dichloromethane at 25℃; for 24 h;
实验步骤：加入9H-咔唑（1）（5.00g，29.9mmol）的二氯甲烷溶液，氯化叔丁基（6.6ml，59.8mmol）和氯化铝（4.00g，29.9mmol）。 在室温下搅拌24小时（25℃，等等）后，倒入冰水（100mL）中。 用二氯甲烷萃取，用无水硫酸钠干燥，过滤，得到溶剂，在室温减压下从滤液中蒸馏出粗产物。 粗产物用石油醚，3,6-二叔丁基-9H-咔唑重结晶，得到（2a）6.30g（产率：75％）。
