It is found that when the molar ratio of sulphoxide,pyridine and acetyl bromide is 1∶0.6∶0.4,the catalytic effect on the ring-enlargment is the best,and the yield and purity of the final product can reach 76% and 97% respectively at a pH of 1.8 in toluene under refluxing for about 3.5h.
通过正交实验可得出以下结论：当N，N′-双脲-亚砜为2.5∶1，乙酰溴-亚砜为0.4∶1，吡啶-乙酰溴为1.5∶1，回流时间为3.5h，酸化pH值为1.8时，扩环反应结果最好，总收率可达76%，纯度97%以上。
