The development of a new and practical synthesis for a farnesyltransferase inhibitor 1 is described. The new route started from 2-nitro-5-cyanotoluene (9) and afforded desired 1 in eight chemical transformations. The key step involved formation of sulfonamide 13 from a hindered β-hydroxyamine 12 through an in situ protection of the hydroxyl group by forming TMS ether. Ultimately, this new route was
描述了法呢基转移酶抑制剂1的新的实用合成方法的开发。新路线从2-硝基-5-氰基甲苯(9)开始,并在八次化学转化中获得所需的1。关键步骤涉及通过形成TMS醚原位保护羟基,由受阻的β-羟胺12形成磺酰胺13。最终,该新路线成功地证明可产生> 10 kg的API,总收率达29%。
