| 提纯方法 | The hydrochlorde can be recrystallised from small volumes of EtOH. Alternatively it is dissolved in EtOH, filtered, Et2O is added; filter the crystalline salt off under N2 and dry it in a vacuum desiccator over H2SO4. The salt is deliquescent and should be stored in a tightly stoppered container. Its solubility in H2O is 10% at room temperature and it is soluble in Me2CO. The free base reacts strongly alkaline in H2O. It has λmax 224nm (ε 4000) in H2O. The picrate has m 252℃ (sintering at ～245℃).
