The compound you actually want is indane, and not indene. I suggest you make phenylpropanoic acid (friedel-craft alkylation with 3-chloropropionic ester followed by hydrolysis, or make the cinnamic acid and reduce it), convert it to the acid chloride and cyclize to 1-indanone via friedel-craft acylation, and finally reduce the ketone with Zn/Hg or Hydrazine/KOH.

You will find details and inspiration in http://www.maps.org/publications//1991_johnson_2.pdf and in http://www.maps.org/publications//1990_nichols_2.pdf

Indene is a very cheap unwatched industrial chemical, you should be able to find it if you look around.
