The preparation of new RSV inhibitors required an efficient synthesis of (R)-2-methylazepane ((R)-1) amenable to large-scale production to support preclinical studies. After consideration of different options, an efficient five-step synthesis relying on the preparation of the racemic N-Boc precursor and its purification by chiral SFC was developed and successfully implemented on a 400 g scale.

目的合成(R)-2-甲基氮杂环庚烷

制备新的RSV抑制剂需要有效合成适合大规模生产的(R)-2-甲基氮杂环庚烷((R-1),以支持临床前研究。在考虑了不同的选择之后,开发了一种有效的五步合成方法,该方法依赖于外消旋N- Boc前体的制备及其通过手性SFC的纯化,并成功实现了400 g的规模。
