Can not remove base category slug from url on WordPress site

I would be very grateful if you tell me when is my mistake. This is my .htaccess file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

RewriteRule ^category/shopcategory1/(.*)$ http://ift.tt/2BJLOXD [L,R=301]
RewriteRule ^shopcategory1/$ /category/shopcategory1/ [L]
</IfModule>
# END WordPress

But all the same there is no redirection.
