Reaction Steps

L-Alanine cetyl ester p-toluenesulfonate was synthesized in the same manner as described in Example 18 for the synthesis of an L-alanine alkyl ester p-toluenesulfonate, except that 13.3 g (0.055 mole) of cetyl alcohol was used in place of myristyl alcohol. The resulting L-alanine cetyl ester p-toluenesulfonate was dissolved again in 200 ml of benzene, and this solution was treated three times with 300-ml portions of 0.1N NaOH. Thereafter, the benzene layer was isolated and washed thoroughly with water. After washing with water, the benzene layer was isolated and dried overnight over anhydrous sodium sulfate. After drying, the benzene layer was filtered and the resulting benzene solution was evaporated to remove the solvent. Thus, there was obtained 14.86 g (94.8% yield) of purified free L-alanine cetyl ester in the form of an oily material. An infrared absorption spectrum of the free L-alanine cetyl ester thus obtained is shown in FIG. 5. In this figure, the peaks 12 and 13 indicate the C=O stretching and C--O stretching vibrations originating from the ester linkage. The peaks 14, 15 and 16 indicate the NH stretching, NH deformation and C--N stretching vibrations, respectively, of a primary amine. The peak 17 indicates the CH deformation vibration.
