合成路线1
该中间体在本合成路线中的序号：(VI)The condensation of 1-(benzylideneamino)imidazolidine-2,4-dione (I) with 1-bromo-4-chlorobutane (II) by means of NaH in DMF at 100 C yields 1-(benzylideneamino)-3-(4-chlorobutyl)imidazolidine-2,4-dione (III), which is treated with NaI in refluxing acetone affording the corresponding 4-iodobutyl derivative (IV). The thermal condensation of (IV) with 1-methylpiperazine (V) in refluxing DMF gives the expected condensation product (VI), which is debenzylated by hydrogenation with H2 over Pd/C in 2N HCl giving 1-amino-3-[4-(4-methylpiperazin-1-yl)butyl]imidazolidine-2,4-dione (VII). Finally, this compound is condensed with 5-(4-chlorophenyl)furan-2-carbaldehyde (VIII) in DMF at room temperature.
