A process of preparing a compound of formula (I), wherein B is chosen from OH, NH2, NHR, H or halogen; D is chosen from OH, NH2, NHR, H, halogen or SCH3; R is an optionally substituted alkyl, aralkyl or aryl group; and Z is selected from OH, hydrogen, halogen, hydroxy, SQ or OQ, Q is an optionally substituted alkyl, aralkyl or aryl group; or a tautomer thereof; or a pharmaceutically acceptable salt thereof; or an ester thereof; or a prodrug thereof, which comprises reacting a compound of formula (II) with an anion produced by abstraction of the bromine or iodine atom from a compound of formula (XIX), to form a compound of formula (XX). The compound of formula (XX) is N- and O-deprotected to obtain the compound of formula (I).
制备式(I)化合物的过程,其中B从OH、NH2、NHR、H或卤素中选择;D从OH、NH2、NHR、H、卤素或SCH3中选择;R为可选取代的烷基、芳基烷基或芳基基团;Z从OH、氢、卤素、羟基、SQ或OQ中选择,Q为可选取代的烷基、芳基烷基或芳基基团;或其互变异构体;或其药物可接受盐;或其酯;或其前药。包括将式(II)化合物与从式(XIX)化合物中提取溴或碘原子所产生的阴离子反应,以形成式(XX)化合物。将式(XX)化合物进行N-和O-去保护即可获得式(I)化合物。
