Reaktionsschritte

In methanol (15 ml) were dissolved 2-amino-5-chloro-α-(3-tert-butoxycarbonylaminomethylphenyl)benzyl alcohol produced in Example 1-(2) (0.5 g) and 4-benzyloxyphenylacetaldehyde (0.4 g). To the solution were added acetic acid (0.1 g) and, subsequently, cyano sodium hydride (0.11 g). The mixture was stirred for 40 minutes at 60° C. The reaction mixture was diluted with ethyl acetate (60 ml), which was washed with water and dried over anhydrous sodium sulfate. The solvent was distilled off to leave 2-[2-(4-benzyloxyphenyl)ethyl]amino-α-(3-tert-butoxycarbonylaminomethylphenyl)-5-chloro-benzyl alcohol (0.45 g) as a colorless oily product.
