Site not redirecting from www to https

On IIS7, my website is not redirecting from www.example.com to https://example.com

Instead it tries to open https://www.example.com

Here is the web.config file

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
        <rules>
                <clear />

                    <conditions> 
                        <add input="{HTTP_HOST}" pattern="^example\.com$" negate="true" /> 
                    </conditions> 
                    <action type="Redirect" url="https://example.com/{R:1}" /> 
                </rule>

                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" appendQueryString="false" />

                    </conditions>
                    <action type="Rewrite" url="/" />
                </rule>
        </rules>
        <outboundRules>
            <preConditions>
