Versuchsvorschrift

N-(2-Imidazolidinylidene)-N'-(2-methoxyphenyl)urea.hydrochloride, m.p. 197°-199.5° C., by reacting 2-iminoimidazolidine (prepared from 2-iminoimidazolidine hydroiodide and lithium hydride) and 2-methoxyphenyl isocyanate at about 5° to 10° C. to obtain a N-(2-imidazolidinylidene)-N'-(2-methoxyphenyl)urea product, followed by reacting the urea base with methanolic hydrogen chloride and recrystallizing first from methanol/2-propanol, then twice from methanol ether.

Aufarbeitung

  1. customat about 5° to 10° C.
