製法・合成法
純化方法
Recrystallise it from freshly distilled Me2CO, wash the crystals with dry Et2O and dry them in a vacuum desiccator over P2O5. RF 0.4 on paper chromatography with CHCl3/EtOH (2:8) as solvent and developed with ammoniacal AgNO3. It also crystallises in needles from EtOAc containing a few drops of Me2CO. It is hygroscopic and should be stored under dry conditions. [Bachmann et al. J Am Chem Soc 73 2775 1951, Walter et al.
