Remove publishing capability from user IDs

I’m trying to remove the capability of users other than the admin (ID number 1) to add a page, I know that there are plugins which you can edit the role but in my case I need the users to be ‘Administrator’ role but I need to remove some capabilities. I have the following code:

function modify_capabilities()
{
	global $userdata;
	get_currentuserinfo();
  $userdata->ID != 1 ->remove_cap('publish_pages');

  // for posts it should be:
  // $editor_role->remove_cap('publish_posts');

  // to add capabilities use add_cap()
}

add_action('admin_init','modify_capabilities');

but I’m not sure why it isn’t working. Please help fix the code, thanks

Note: The reason why it needs to be Administrator role because a specific plugin I use only displays reports to ‘Administrator’.

[No bumping, thank you.]
