-You could dissolve in naphtha and freeze precipitate.
-Mini A/B is another route then use a different solvent.
-or you could use another solvent like d-limo and precipitate out a salt form like benzoate, alternatively you could use xylene and salt out the DMT with fumaric acid (with acetone). Look up FASA.
These will form DMT salts though, so if you want freebase again you could rebase and pull again.
