Changing the front page title

I’m trying to change the page title for the Front page, using the static page option, the code I’m using is

<?php
if (is_front_page()) {?>
<title><?php bloginfo(‘name’); ?> | Welcome to my blog</title>
<?php }
else {?>
<title><?php bloginfo(‘name’); ?> <?php wp_title(‘|’, true, ‘left’); ?></title>
<?php } ?>

any ideas
