Making field required in convert lead page

Hello all!

So i need to set field required on convert page, maybe some one help me?

 'panels' =>array (
        'LNK_NEW_OPPORTUNITY' => array (
            array (
                array('name' => 'name', 'displayParams' => array('required' => true)),

This is my code, that doesn’t work for me.

Also on Opportunity module this field is required and on convert page it’s marked as required. But when i save the record without filled ‘name’ field it’s saved.
