Conditions have been developed for the synthesis of N-trifluoroacetyl-beta- alanine, N-tifluoroacetylalanyl chloride, and N-trifluoroacetyl- alanine 4-nitrophenyl ester. These compounds reacted with histidine methyl ester or sodium salt to give N-trifluoroacetyl-beta-alanyl-L-histidine methyl ester CF3CONHCH2CH2 center dot CONHCH( CH2C3H3N2) COOCH3 and N-trifluoroacetyl-beta-alanyl-L-histidine CF3CONHCH2CH2CONHCH center dot(CH2C3H3N2) COOH. Their hydrolysis with a solution of sodium hydroxide in aqueous ethanol, followed by acidification with trifluoroacetic acid, led to the formation of beta-alanyl-L-histidine (L-carnosine).
