| titleOfInvention | Method for producing cyclic urea compound by two-step method |
| abstract | (57) [Summary] [Structure] Urea and diamine in which amino groups are separated by 8 to 22 atoms are mixed at a molar ratio of about 1: 1 at a temperature of 120 to 140 ° C until 1 mol of ammonia is generated. The obtained intermediate with a solvent at a temperature of 160-200. A method for producing a cyclic urea compound, which comprises slowly heating at 0 ° C. for cyclization. [Effect] A macrocyclic urea compound can be easily synthesized from a commercially available diamine without the need of reacting in an extremely diluted state or synthesizing a diisocyanate derivative of diamine. |
