Downstream synthetic route of 14691-88-4

14691-88-4, As the paragraph descriping shows that 14691-88-4 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14691-88-4,4-Amino-2,2,6,6-tetramethylpiperidine 1-Oxyl,as a common compound, the synthetic route is as follows.

To a solution of 3,5-t-butyl-4-hydroxyl benzoic acid (2.50 g, 10 mmol), 4-amino-TEMPO (1.55 g, 9.1 mmol) and DMAP (0.5 g, 4 mmol) in CH2Cl2 (50 mL) At 0-5¡ã C., DCC (2.30 g, 1 mmol) in dichloromethane (50 mL) was added dropwise. After addition is complete, the mixture was stirred at room temperature overnight. The reaction mixture was filtered and the filtrate was washed with 1N HCl (20 mL) and dried over MgSO4. After MgSO4 was filtered off, the solvent was removed in vacuum to give a solid The solid was purified by column chromatography (silica gel, EtOAc/Hexane). The product is an orange solid (1.3 g). The yield was 35percent.
