[0056] The method of the present invention can include the synthesis of 1H-thieno[3,4-d]imidazolin-2(3H)-one in a single reaction mixture. The synthesis method of 1H-thieno[3,4-d]imidazolin-2(3H)-one according to the present invention includes the mechanism shown below:

[0057] This first reactant compound, second reactant compound, solvent and base are present in the reaction mixture. In the above reaction, 3,4-diaminothiophene dihydrochloride is shown as sodium carbonate (Na 2 CO 3 ) Reacts in the presence of a base to form 3,4-diaminothiophene, which reacts with the second reactant compound of urea shown above to form 1H-thieno[3,4-d]imidazoline-2(3H)- ketone.

[0058] The method of the present invention also includes the synthesis of imidazolinone selenophene derivatives. In this embodiment of the present invention, the reaction of 3,4-diaminoselenophene dihydrochloride is as follows:

[0059] In the above reaction, 3,4-diaminoselenophene dihydrochloride is shown as sod...

Embodiment 1

[0078] According to the method of the present invention, the compound 1H-thieno[3,4-d]imidazolin-2(3H)-one is prepared in a single reaction mixture. In Example 1, triethylamine was used as a base to release 3,4-diaminothiophene from dihydrochloride. Urea is used as the second reactant compound containing a carbonyl group.

[0079] Set the quantity to 0.1922g (1.028×10 -3 mol) 3,4-Diaminothiophene dihydrochloride ("DAT-HCl") and 0.1866g (3.11×10 -3 mol; 3.02 equivalents based on DAT-HCl) Urea was added to a 50 mL three-necked flask equipped with magnetic stirring and reflux condenser. The flask was purged with nitrogen for 15 minutes, after which 20 mL of 1,3-dimethyl-2-imidazolidinone ("DMI") was added with a syringe under stirring. Heat the contents to 50℃, at this time add 0.45mL (0.327g, 3.23×10 -3 mol; 3.14 equivalents based on DAT-HCl) triethylamine. The temperature of the flask was raised to 115-120°C and kept in this temperature range for 4 hours. After cooling and filte...

Embodiment 2

[0082] According to the method of the present invention, 1H-thieno[3,4-d]imidazolin-2(3H)-one is prepared in a single reaction mixture. Example 2 uses 4-(dimethylamino)pyridine, an alternative base of Example 1, as the base to release 3,4-diaminothiophene from the dihydrochloride. In addition, Example 2 uses 1,1'-carbonyldiimidazole as the second reactant compound.

[0083] Set the quantity to 0.1934g (1.034×10 -3 mol) 3,4-Diaminothiophene dihydrochloride (DAT-HCl), 0.4862g (3.001×10 -3 mol; 2.90 equivalents based on DAT-HCl) 1,1'-carbonyldiimidazole, and 0.3957g (3.243×10 -3 mol; 3.14 equivalents based on DAT-HCl) 4-(dimethylamino)pyridine was added to a 50 mL three-necked flask equipped with magnetic stirring and reflux condenser. The flask was purged with nitrogen for 15 minutes, and then 20 mL of 1,3-dimethyl-2-imidazolidinone (DMI) was added with a syringe while stirring. The temperature of the flask was raised to 115-120°C and kept in this temperature range for 4 hours. Afte...
