You can't.

A pagename cannot contain any of the following characters: # < > [ ] | { } _ (which have special meanings in Wiki syntax), the non-printable ASCII characters 0–31 (dec), the delete character 127, the Unicode replacement character U+FFFD (�), or HTML character codes such as &amp;amp;. A pagename also cannot contain 3 or more continuous tildes, as these are used for marking signatures on wikis.

I tried with the HTML replacement &lt; and a percent code %3E just to be sure, and neither works.
