What is the correct way to cut off part of the url in .htaccess?

Question

htaccess

There is a URL like site.ru/korzina/add_korzina.html
It needs to be cut to look like site.ru/korzina
I wrote this rule, but it doesn't work:

RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /add_korzina\.html\ HTTP/
RewriteRule ^add_korzina\.html$ https://site.ru/korzina [R=301,L]

Question: how to make it work?
