You just cannot do that. Cross-site scripting is not allowed in most browsers.
You can, however, communicate with the other window via cross-document messaging described here: https://developer.mozilla.org/en/DOM/window.postMessage
The most you can to is to send a message from the popup to the opener and listen for such message in the opener. The opener then has to change its location on its own.
// popup: window.opener.postMessage('replace your location', '*');
// opener: window.onmessage = function (e) {
if (e.data === 'replace your location') {
window.location.replace(...);
}
};
