Tag: 26364-65-8

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.26364-65-8,2-Cyanoimino-1,3-thiazolidine,as a common compound, the synthetic route is as follows.

General procedure: Thiazolidin-2-ylidene-cyanamide (0.317 g, 2.50 mmol) inacetonitrile (20 mL) was dropwise added to a stirred solutionof substituted benzyl bromide (2.5 mmol) and 14 mL NaOHaqueous solution (1 M). The mixture is stirred at room temperaturefor 8-10 h. The soild was collected by filtration,washed with n-hexane and dried in vacuo.

As the paragraph descriping shows that 26364-65-8 is playing an increasingly important role.

26364-65-8, 2-Cyanoimino-1,3-thiazolidine is a thiazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: In a 100 ml three-necked flask equipped with a thermometer and an electromagnetic stir bar were added 0.01 mol of anhydrous K2CO3 powder, 0.01 mol of 2-nitroaniline,30 ml of acetone,A solution prepared by dissolving 0.01 mol of 1,3-dimethyl-4-pyrazolecarboxylic acid chloride in 20 ml of acetone was gradually added dropwise at low temperature (0 to 5 C), and the reaction was continued at room temperature for 10 hours. The reaction mixture was filtered under reduced pressure, and the resulting filtrate was decompressed to yield a crude product of compound Q110907. The crude product of compound Q110907 was recrystallized from acetonitrile to give the compound (Q110907) in a yield of 42.9%. Using Thiazoline-2-imino-cyanamide instead of 2-nitroaniline; Acetonitrile was used as the reaction solvent; reaction temperature was 45 ¡À 5 C; reaction time was 8 hours; toluene recrystallization
