• läuterung methode

  Purify indolizine through an alumina column in *C6H6 and elute with *C6H6 (toluene could be used instead). The eluate contained in the fluorescent band (using UV light 365mn) is collected, evaporated and the crystalline residue is sublimed twice at 40-50o/0.2-0.5mm. The colourless crystals darken on standing and should be stored in dark sealed containers. If the original sample is dark in color then it should be covered with water and steam distilled. The colourless crystals in the distillate are collected and dried between filter paper and sublimed. It protonates on C3 in aqueous acid. It should give one fluorescent spot on paper chromatography (Whatman 1) in 3% aqueous ammonia and in n-BuOH/AcOH/H2O (4:1:1). The picrate has m 101o from EtOH.
