Think its only about five stops on line 2 to get to Beijing North where the train to the wall leaves. Line 2 also has most of the tourist sites on it, and you're also a short walk to Sanlitun.
Edit: Dongzhimen also has 'Ghost' Street with hundreds of restaurants on it - famous for frog hot pot!
Yeah, I could endorse that plan for the OP. In fact, the entire NE section of Line 2 has interesting spots along it, and Dongzhimen is right at the bend.
