Question

I want add a new Draft button in Product Edit page (located between Back and Add Attribute)

I am able to add by following the tutorial : magento2-how-to-add-custom-button-in-product-edit-form

But, I am unable to add the link to my custom controller. Does anyone have any advice please.

The product form is generated via ui-components.
The ui component name for product form is view/adminhtml/ui_component/product_form.xml.

You need to create a file with the same name and path in your own module with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <argument name="data" xsi:type="array">
        <item name="buttons" xsi:type="array">
            <item name="button-unique-identifier-here" xsi:type="string">[Namespace]\[Module]\Block\Adminhtml\Product\Edit\Button\CustomButton</item>
        </item>
    </argument>
</form>

Then create the class [Namespace]\[Module]\Block\Adminhtml\Product\Edit\Button\CustomButton in the file [Namespace]/[Module]/Block/Adminhtml/Product/Edit/Button/CustomButton.php

<?php 
namespace [Namespace]\[Module]\Block\Adminhtml\Product\Edit\Button;
use Magento\Catalog\Block\Adminhtml\Product\Edit\Button\Generic;
class CustomButton extends Generic
{
    public function getButtonData()
    {
        return [
            'label' => __('Enter Your button label here'),
            'on_click' => "alert('it works..')",
            'class' => 'primary',
            'sort_order' => 100
        ];
    }
}

Your ui component file should be merged with the main file and your buttons should appear among the other buttons.
