純化方法
Purify it by distillation under a vacuum and by recrystallisation from Et2O/hexane. [Kauffmann et al. Justus Liebigs Ann Chem 656 103 1962, Potts & Burton J Org Chem 31 251 1966.] The mono-hydrochloride has m 183o(dec) from aqueous HCl, and the di-hydrochloride has m 214-215o. [Beilstein 22 II 487, 22 III/IV 7025, 22/14 V 486.]
