Reaction Steps

A mixture of 33 g of N-butylamine (0.45 mol) and 19 g of diisopropylcarbodiimide (0.15 mol) is heated at reflux for 3 hours 30 minutes. GC analysis then shows a conversion of more than 99.5% of the diisopropylcarbodiimide. The final mixture, which is colorless, is concentrated at 60° C. under 20 mbar for 2 hours, to give 29 g of a colorless and virtually odorless liquid of low viscosity, which corresponds to the expected guanidine (96.7% yield).
