149057-19-2, Step 4 Synthesis of piperazine-1,2,4-tricarboxylic acid 4-benzyl ester 1-tert-butyl ester 2-methyl ester K2CO3 (910 mg, 6.6 mmol) was added to a stirred solution of piperazine-1,2,4-tricarboxylic acid 4-benzyl ester 1-tert-butyl ester (1.2 g, 3.3 mmol) in DMF (10 mL) at ambient temperature. To the above mixture was added at 0 C., CH3I (1.4 g, 9.9 mmol) and stirred 20 C. for 2 hr. The reaction mixture was diluted with cold water, extracted with ethyl acetate and dried over sodium sulphate, concentrated under reduced pressure to afford 1.2 g(96.4%) of piperazine-1,2,4-tricarboxylic acid 4-benzyl ester 1-tert-butyl ester 2-methyl ester.
149057-19-2 4-((Benzyloxy)carbonyl)-1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid 2756778, apiperazines compound, is more and more widely used in various fields.
