Synthesis of angiotensin II AT1 receptor antagonist azilsartan is described. The results include reinvestigation of the described process as well as its novel modification. This new process includes transformation of the CN group into amidoxime moiety by aqueous hydroxylamine, its treatment with alkyl chloroformates and a base‐initiated cyclization of the formed (alkoxycarbonyl‐oxy)carbamimidoyl intermediates
描述了血管紧张素II AT 1受体拮抗剂阿齐沙坦的合成。结果包括对所描述的过程及其新颖的修改方法进行了重新研究。这一新方法包括通过羟胺水溶液将CN基团转变为mid肟肟部分,用烷基氯甲酸酯处理以及形成的(烷氧基羰基氧基)氨基甲酰氨基中间体的碱引发环化反应。到目前为止,已鉴定出几种未描述的副产物,其中一些已合成并适当表征为潜在杂质。
