You could do this more easily in an async Click handler:

private async void Button_Click(object sender, RoutedEventArgs e)
{
    var button = (Button)sender;
    button.IsEnabled = false;

    await Task.Run(() =>
    {
        // perform time-consuming action
        Thread.Sleep(5000); // just for test
    });

    button.IsEnabled = true;
}
