Reaction Steps
A solution of N-[m-(p-amidinobenzamido)benzoyl]-3-(t-butoxycarbonyl)-L-alanine methyl ester hydroidide in CH2Cl2 /trifluoroacetic acid is left to stand at room temperature for 3 hours. After removal of the solvent and recrystallization of the residue from ethanol/ether there is obtained (S)-3-[m-(p-amidinobenzamido)benzamido]-3-(methoxycarbonyl)propionic acid trifluoroacetate in the form of a colourless solid. Yield: 75%, m.p. 132°-134° C. (decomposition). MS: 413 (M+H)+.
