The other answers are outdated since Apple changed the UI in iTunes Connect. This is how it works now:

1. You first must upload a new binary using xCode or Application Builder (having a greater build number otherwise you won't be able to upload)
2. A "remove app version" button will appear in itunes connect, in the app details page, it is pretty visible and emphasized, you can't miss it. This will not actually delete the app version... it will just reject your binary. Your app version with all the details will be preserved.
3. After you press that your app status will be "developer rejected". Select the newly uploaded build for the new app version and click save.
4. Now your app status will be "preparing for submission". Press submit for review.

Note that the steps are referring to the case when you are submitting a new app version of an app but I imagine the steps are very similar for the case of a new app.
