21043-40-3, 1-Cyclopentylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: To a mixture of intermediate 7 (500 mg, 1.3 mmol), EDC¡¤HCl (300 mg, 1.5 mmol) and HOBt (210 mg, 1.5 mmol)) in dried CH2Cl2 was added appropriate amine (1.5 mmol), and stirred at rt for overnight. After complete reaction, the reaction mixture was concentrated in vacuo and purified via column chromatography to afford appropriate 2-(2-(tritylamino)thiazol-4-yl)acete amide. The above product was dissolved in the mixture of 5 mL of acetic acid and 0.1 mL of water. The solution was heated under argon at 60 C for 1 h, and then allowed to cool to rt. The resulted dark solution was diluted with 20 mL of water, the triphenylmethanol was removed by extraction with Et2O. The watery phase was adjusted to pH8 with saturated Na2CO3 solution, and extracted with CH2Cl2. The organic extract was dried over anhydrous MgSO4, evaporated to dryness in vacuo. The resulting brown oil was purified via column chromatography with CH2Cl2-MeOH as eluent to afford appropriate 2-(2-(amino)thiazol-4-yl)acete amide 8a-f., 21043-40-3

The synthetic route of 21043-40-3 has been constantly updated, and we look forward to future research findings.
