Crystallise it three times from acetone and dry it under vacuum at ca 45o. Alternatively, keep it in contact with NaOH pellets for 3hours, with occasional shaking, decant and fractionally distil it [Mod et al. J Phys Chem 60 1651 1956]. It also recrystallises from CH2Cl2 on addition of pet ether. [Marzilli et al. J Am Chem Soc 108 4830 1986, Beilstein 22/9 V 210.]
