合成路线1
该中间体在本合成路线中的序号：(III)Alkylation of 3-nitrophenol (I) with methyl bromoacetate (II) in the presence of K2CO3 provided phenoxyacetate (III). Then, reduction of the nitro group of (III) by hydrogenation on Pd/C gave amine (IV), which was subsequently condensed with N-tert-butoxycarbonyl glycine (V) on treatment with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide.HCl (EDC) to afford amide (VI). Alkylation with bromoacetamide (VII) in the presence of NaH in THF provided (VIII), and removal of the Boc protecting group with trifluoroacetic acid gave amine (IX). This amine was condensed with 3-tolyl isocyanate (X) to give urea (XI). Then, alkaline hydrolysis of the ester group afforded acid (XII), which was finally condensed with N-methylaniline (XIII) to yield the target compound.
