Deny access per extension in multiple locations

[nfn]

Hello,

I have this rule in apache that denies access to some extensions in
multiple locations.
I have this .htaccess in some folders like uploads, docs, pdfs.


    Order allow,deny
    Deny from all


How can I join this in one line to deny access in multiple folders for
these extensions?

I was trying this without success:

location ~ /(uploads/|docs/|pdfs/)*\.(php|cgi|pl|php3|php4|php5)$ {
  root /srv/www/portaldasviagens.com/public;
  deny    all;
}

Thanks
