Thank you; that is very helpful. How did you find that link?
There was a 1.5 mole to mole ratio of bromine over the anilide. Having already purchased the starting material, I think that I will live with bromination of the aromatic ring. If I want to avoid bromine on the ring, it may be possible to make N-phenylacrylamide from 2,3-dibromopropionic acid, aniline, and SO2Cl, based on the chemistry of similar compounds.
