合成路线1
该中间体在本合成路线中的序号:(I)The cyclization of dimethyl 2-methoxymalonate (I) with formamidine (II) by means of sodium methoxide in methanol gives the dihydroxypyrimidine (III), which by reaction with POCl3 is converted into the dichloropyrimidine (IV). The condensation of (IV) with 5-fluoro-3-[3-(1-piperazinyl)propyl]-1H-indole (V) by means of DIPEA in refluxing acetonitrile affords intermediate (VI), which is finally dechlorinated by hydrogenation with H2 over Pd/C in aqueous ethanol.
