Htaccess Redirect (from A File With Spaces)

I'm trying to redirect from a filename that contains spaces using .htaccess

for example, I want to redirect /test 2.html to http://example.com

I've tried:

ReDirect /test 2.html http://example.com
ReDirect /test 2.html http://example.com
ReDirect /"test 2".html http://example.com
ReDirect /'test 2'.html http://example.com
ReDirect /test%202.html http://example.com
ReDirect /"test 2.html" http://example.com
ReDirect /'test 2.html' http://example.com

And a few others. I can't seem to get the syntax right, and always end up getting an internal server error message. Anyone have any ideas?
