Draw it just like you did aspirin, but where you would put the CH3 for the acetyl group, put a benzene ring instead. A possible name is ortho-(benzoyloxy)benzoic acid.

The water is first added to react with the excess acetic anhydride. Water will react with that to form acetic anhydride. The aspirin that you're making is only slightly soluble in cold water. So the water also makes the aspirin product preciptate so you can collect it.
