調製方法
純化方法The extract is filtered and evaporated to dryness, then the powdered residue is completely dried in a vacuum desiccator over silica gel. Its solubility in Et2O is 33.5g in 750mL. It can be recrystallised from *C6H6 (solubility is: 1.9g in 30mL of *C6H6, and 33.5g will dissolve in 750mL of anhydrous Et2O). [Traynham & Dehn J Org Chem 23 1545 1958, Haszeldine J Chem Soc 584 1951.] Store it in the dark. It is also soluble in trifluoroacetic acid (15.2% at 30o), toluene, o-xylene and dioxane [Hara & Cady J Am Chem Soc 76 4285 1954]. [Beilstein 2 IV 461.]
