I believe that phenolphtalein is usualy made by combining phenol and phtalic anhydride with an acid, however I am not sure that this synthesis can be
reversed. If you are looking to make phtalic anhydride you can watch this video by nurdrage on making luminol (phtalic anhydride is produced in one
of the steps on the way to make luminol)
