With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.129799-15-1,Methyl 1-Boc-piperazine-2-carboxylate,as a common compound, the synthetic route is as follows.
Step 6 Synthesis of 4-(5-Fluoro-2-trifluoromethyl-benzoyl)-piperazine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester DIPEA (430 mg, 0.58 mL, 3.27 mmol) followed by HOBT (121 mg, 0.9 mmol) and EDCI (230 mg, 1.22 mmol) were added to a stirred solution of 5-Fluoro-2-trifluoromethyl-benzoic acid (170 mg, 0.82 mmol) in DMF (2.0 mL) at room temperature. After 2 minutes 2 minutes piperazine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester (200 mg, 0.82 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was then added, filtered the solid precipitated to afford 305 mg (85.9%) of 4-(5-Fluoro-2-trifluoromethyl-benzoyl)-piperazine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester.
129799-15-1, As the paragraph descriping shows that 129799-15-1 is playing an increasingly important role.
