该中间体在本合成路线中的序号：(IV)The reductive amination of 2-nitrobenzaldehyde (I) with 4-amino-1-benzylpiperidine (II) in the presence of NaBH4 gave amine (III). Subsequent hydrogenation of the nitro group of (III) over Rh/C afforded (IV), which was converted to oxoquinazoline (V) upon treatment with carbonyl diimidazole in hot DMF. Hydrogenolysis of the benzyl protecting group of (V) yielded intermediate (VI).
