Need to redirect website with htaccess

I am trying to redirect my site to https://www.mysite.com/ from https://www.mysite.com/wordpress1, which is where it is now. Here is my htaccess code:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress1/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress1/index.php [L]
</IfModule>

Anyone have any tips?
