Application:

Boc-His(Dnp)-OH·IPA (CAS: 25024-53-7), the Dnp group is stable to HF and TFMSA. Amino acids and derivatives, peptide synthesis, pharmaceutical intermediates, biochemical reagents. As a typical derivative of L-Histidine, Boc-His(Dnp)-OH·IPA has received more and more attention in the field of pharmaceutical and chemical industry.
Preparation Using 2,4-Dinitrophenyl-L-Histidine as the starting material, the target compound N-(tert-Butoxycarbonyl)-1-(2, 4-Dinitrophenyl)-L-Histidine was prepared by amino protection reaction with ditert-butyl dicarbonate. Fig. 1 experimental operation of synthesis reaction formula of N-(tert-Butoxycarbonyl)-1-(2, 4-Dinitrophenyl)-L-Histidine: 2,4-Dinitrophenyl-L-Histidine is dissolved in 100mL of sodium hydroxide aqueous solution, 200mL of tetrahydrofuran and 250g of ditert-butyl dicarbonate are sequentially added, the pH value is controlled to 8-9, and after 12h of reaction, ethyl acetate is extracted twice, 500mL each time; HCI is used to acidify the aqueous phase to a pH value of 1-2, and ethyl acetate is used to extract the product 3 times, 500mL each time. The ester layers are combined and washed twice with saturated brine, 200 ml. Dry with anhydrous sodium sulfate for 12h, filter, concentrate and crystallize, and dry at 40-50℃ to obtain N-(tert-Butoxycarbonyl)-1-(2, 4-Dinitrophenyl)-L-Histidine.
