Apache :: Create Redirect To Non Existing Page

I need to create a redirect to a non existing page.

Here is my code and the site is on shared hosting

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteRule ^index2.php#!(.*)$ /index2.php/$1 [R=301,L]
</IfModule>

This would be [URL] ....

I would like to redirect Every request with "#!string" to new url (same page) - [URL] ....

I know that the code above needs

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

to be added but it doesnt even makes the redirect to 404. The url doesn't change.
