I would not recommend this. I was under the impression I was receiving 100 mg of the title compound but I believe it is 100 mg of 50% w/w in toluene, so 50 mg. I was only able to recover <40 mg and some of the product in the ampoule was not toluene soluble. There is also no indication of its purity that I can find.
