A medicinal chemistry program to develop potent and selective LABA compounds required the synthesis of both carbon-14 and stable-isotope labelled materials. Carbon-14 labelled AZD7307 was successfully synthesised in 6 steps from [14C]chloroacetyl chloride in an overall radiochemical yield of 10%. In addition, the synthetic route of a stable labelled isotopomer of AZD7307 is also described and synthesised in four linear steps from [13C6]cyclohexylamine hydrochloride in an overall yield of 12%.
开发有效且选择性 LABA 化合物的药物化学项目需要合成碳 14 和稳定同位素标记材料。 由[14C]氯乙酰氯经6步成功合成碳14标记的AZD7307,总放射化学产率为10%。此外,还描述了AZD7307的稳定标记同位素异构体的合成路线,并以[13C6]环己胺盐酸盐为原料,分四步线性合成,总产率为12%。
