I understand you may have a good reason for putting the Adsense in that location, but be aware that the click through rate will probably be quite low. The Adsense help pages have a "heat map" showing which page areas tend to get more eyeball time and clicks.
Generally, hot spots are at the beginning of the content or where the user expects to see navigation. These spots may not create the best user experience, because you are placing ads where content or navigation is expected - you'll have to decide whether it's worth it.
