Coupling between methyl 2-amino-5-phenylpentanoate (I) and N-Boc-alanine (II) affords dipeptide (III). Deprotection of (III) with trifluoroacetic acid yields amine (IV), which is then acylated with (S)-3,5-difluoromandelic acid (V), producing amide (VI). Finally, ester group reduction using LiBH4 leads to the desired alcohol.
