A solution of 2(S)-[Nα -[2(S)-[N-methyl-N-{2-(N-t-butoxycarbonyl-N-methylamino)ethyl}aminocarbonyloxy]-3-phenylpropionyl]-Nα -methyl-L-histidyl]amino-1-cyclohexyl-3(S)-hydroxy-6-methylheptane (114 mg) in trifluoroacetic acid (10 ml) was stirred at 0° C. for 1 hour. After evaporation of the solvent, the residue was dissolved in ethyl acetate (20 ml) and the solution was washed with 1 M sodium bicarbonate solution and water successively, and dried over magnesium sulfate. Evaporation of the solvent gave 2(S)-[Nα -[2(S)-{N-methyl-N-(2-methylaminoethyl)aminocarbonyloxy}-3-phenylpropionyl]-Nα -methyl-L-histidyl]amino-1-cyclohexyl-3(S)-hydroxy-6-methylheptane (88 mg) as an amorphous powder.
