合成路线1
Swern oxidation of 1-(4-pyridinyl)-4-piperidinemethanol (I) affords aldehyde (II). Reductive amination of (II) with the (R)-diaminopropionic acid derivative (III) in the presence of NaBH(OAc)3 yields (IV). Subsequent acylation of (IV) with bromoacetyl chloride (V) provides bromoacetamide (VI). Acidic cleavage of the N-Boc group of (VI), followed by cyclization in the presence of triethylamine leads to piperazinone (VII). Sulfonylation of amine (VII) with 6-chloro-2-naphthalenesulfonyl chloride (VIII) gives (IX). Finally, the target carboxylic acid is obtained by hydrolysis of ethyl ester (IX) under acidic conditions.
