After following Sahil's answer, your status will change to "Developer Rejected". You will need to go into "View Details", click on "Ready to Upload Binary", and follow the steps. This will change your status back to "Waiting for Upload" at which point you will be able to submit a new version.
The other answers are outdated since Apple changed the UI in iTunes Connect. This is how it works now:
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.
Use the "Reject binary" button so you can upload a new one. You'll go back to end of the approval queue.
1) First you have to "Reject the Binary". Now you can edit your App in itunes connect. But before that first upload your changed (new) code. You'll probably have to get a new build number for it.
2) Now comes the tricky part. You have to remove the connection between the App definition in iTunes connect and the binary. It did cost me 25 minutes before I found it where that can be done.
In the details of the App is the build information. When you move over the date, a small stop sign will appear. That is the one you are looking for. Press it and delete the binary from this version.
3) Now press SAVE (otherwise the new binary will not be listed).
4) By using the (+) you can add your new binary.
5) Submit for review again
There is now an information banner in blue (see image above) that let's you know how to remove your app from review.
"You can still edit all information while your version is waiting for review. To submit a new build, you must remove this version from review."
Just one slight correction, when you say "you can't miss it", you underestimated me :-) I've gone through App Store, Features, TestFlight and Activity, and see no button labeled "Remove App Version". In my list of builds, Build # 4 is Waiting for Review, but I want Apple to review Build 6. If I click on Build # 4 ... I have some info about it, but nothing that lets me delete.
