该中间体在本合成路线中的序号：(II)The precursor mesylate (V) was synthesized as follows. Alkylation of phenylacetonitrile (I) using isopropyl bromide in the presence of KOH provided 2-phenylisovaleronitrile (II). Michael addition of ethyl acrylate to the potassium anion of nitrile (II) afforded cyano ester (III). After ester group reduction with LiAlH4, the resultant alcohol (IV) was treated with methanesulfonyl chloride and triethylamine to yield mesylate (V).
