Blog address pages

Hi, this question’s probably already posted somewhere but I really couldn’t find it… so maybe someone can help me out with my blog:

WordPress address is https://www.mysite.com/wordpress
Blog address is https://www.mysite.com

I use
< a href=” < ? php bloginfo(‘wpurl’); ? >/wp-login/”>LogIn in my blog, but now pages direct to https://www.mysite.com/wordpress/wp-login.php instead of https://www.mysite.com/wp-login.php

What should I change this code in?

Thanks.
