Guanidine → HCID 58238472, compound

Participants

Reaction Steps

A mixture of 17.78 g of N-butyl-N-methylamine (0.204 mol) and 21.05 g of dicyclohexylcarbodiimide (0.102 mol) is refluxed for 3 h. GC analysis then shows a conversion of greater than 99.50 of the dicyclohexylcarbodiimide. The colorless final mixture is concentrated at 60° C. under 1 mbar for 2 h so as to give 29.9 g of a colorless and virtually odorless liquid of medium viscosity, corresponding to the expected guanidine (yield 99.70).
