该中间体在本合成路线中的序号:(II)The precursor aldehyde (VI) was prepared as follows. 4-Nitrobenzaldehyde (I) was protected as the ethylene acetal (II) and subsequently reduced by catalytic hydrogenation in the presence of PtO2 to furnish aniline (III). Acylation of (III) with 2-thiophenecarbonyl chloride (IV) provided amide (V). The ethylene acetal group of (V) was then hydrolyzed to the target aldehyde (VI) under acidic conditions.
