show how to synthesize this molecule using benzene,
1-bromocyclopenta-1,4-diene and any other reagents containing less
than two carbons. steriochmistry does matter
this is for organic chemistry 2 so the synthesis should involve
reactions covered in that class such as a diels-alder reaction or
using a organolithium reagent
