该中间体在本合成路线中的序号:(IV)The condensation of 6,7-dimethoxy-4-(1-piperazinyl)quinazoline (I) with 4-bromophenylamine (II) by means of CDI or triphosgene gives the target piperazine-1-carboxamide. Alternatively, the reaction of 4-bromophenylamine (II) with 4-nitrophenyl chloroformate (III) by means of TEA gives the carbamate (IV), which is finally condensed with the quinazoline (I) in hot NMP to yield the target piperazine-1-carboxamide.
