Versuchsvorschrift

A mixture of 1-(5-cyano-2-morpholinophenyl)thiourea (5.2 g), potassium carbonate (8.3 g), a 33% ethanolic solution of dimethylamine (15 ml), lead acetate trihydrate and ethanol (25 ml) was heated under reflux for 3 hours to yield 1,1-dimethyl-2-(5-cyano-2-morpholinophenyl)guanidine (m.p. 125°-127° C.) which was converted into its monofumarate salt [m.p. 223°-225° C. (dec)] which was recrystallised from methanol.

Aufarbeitung

  1. temperatureunder reflux for 3 hours
