合成路线1
该中间体在本合成路线中的序号：(XIV)The aliphatic amino group of 4-aminophenethylamine (VI) was regioselectively protected as the N-Boc derivative (VII) using Boc2O. Subsequent reductive alkylation of aniline (VII) with N-benzyl-4-piperidone (VIII) afforded the anilinopiperidine (IX). The N-benzyl group of (IX) was then removed by transfer hydrogenolysis, and the resulting piperidine (X) was condensed with octyl isocyanate (XI), yielding the corresponding urea (XII). After acidic cleavage of the N-Boc protecting group of (XII), the primary amine (XIII) was condensed with the intermediate epoxide (V) to produce the amino alcohol (XIV). Final desilylation of (XIV) gave rise to the title compound.
