Synthesis of penta-substituted guanidines |
| abstract |
The present invention is the novel synthesis of sterically hindered penta-substituted guanidines by a process in which (1a) an isocyanate is reacted first with a di-substituted amine or (1b) a urea is reacted with two moles of a mono-substituted amine to form a tri-substituted urea followed by (2) treatment of the tri-substituted urea with an activating agent before reacting with a second di-substituted amine in the presence of a base. |
