PROCEDURE

实验过程

A solution of diaminoguanidine hydrochloride (6.28 grams; 0.05 mole) and 2,2,6,6-tetramethyl-4-piperidone monohydrate (17.3 grams; 0.10 mole) in 200 mls. of ethanol 2B was refluxed for a period of 15 hours while stirring. The resulting slurry was cooled to 25° C. and the solid was separated to obtain 10.0 grams of crude 1,3-bis[(2,2,6,6-tetramethyl-4-piperidylidene)amino]guanidine hydrochloride. Recrystallization of the crude hydrochloride from ethanol 2B gave 8.9 grams of white solid, m.p. 210°-220° C. (dec).
