Structural formula:

Synthetic rout:

In the presence of sulfuric acid, the concentrated sulfur was slowly mixed in the hydrobromic acid, then the secondary butanol was added, then refluxed for 2-3 h, the bromate was distilled out, and the distillate was stratified. Got organic, by water, concentrated hydrochloric acid, water, sodium carbonate dilute solution, washed with water, dried with anhydrous calcium chloride, and distilled to collect 90.5-92.5 ℃ distillate.
