N -Hydroxyphthalimide [524-38-9] M 163.1, m 230o, ~235o(dec), 237-240o, 7.0. Dissolve the imide in H2O by adding Et3N to form the salt and while hot, acidify, cool and pour into a large volume of H2O. Filter off the solid, wash it with H2O and dry it over P2O5 in a vacuum. [Nefken & Teser J Am Chem Soc 83 1263 1961, Fieser 1 485 1976, Nefkens et al. Recl Trav Chim, Pays-Bas 81 683 1962] The O-acetyl derivative has m 178-180o (from EtOH). [Beilstein 21/11 V 100.] |
