Chemistry - How to develop a retrosynthesis plan for 2-[(E)-2-(3-bromophenyl)ethenyl]-1,3-benzoxazole?

Extempore, this should be available by the reaction of 3-bromocinnamaldehyde with 2-aminophenol. Samarium triflate as a catalyst might be a good idea.

In any case, I'd start the retrosynthesis at the benzoxazole moiety.
