该中间体在本合成路线中的序号：(IV)N-Boc-2-Aminohexadecanoic acid (I) was reduced to the Boc-aminoalcohol (III) via conversion to the mixed anhydride (II), which was subsequently reduced with NaBH4. Alcohol (III) was protected as the benzyl ether (IV) by alkylation with benzyl chloride in the presence of NaH. After acid deprotection of the N-Boc group of (IV), the resultant primary amine (V) was monoalkylated with ethyl bromide under controlled conditions to afford (VI). Finally, hydrogenolysis of the benzyl ether function of (VI) over Pd/C furnished the title amino alcohol.
