efficient and practical synthesis of a TRPV1 inhibitor bearing a thiazolo[5,4-d]pyrimidine core was developed. The initial synthesis was modified to facilitate acylation of 5-aminopyrimidine and subsequent thiazole formation. The synthesis features an efficient two-pot, five-step process for the construction of the thiazolo[5,4-d]pyrimidine ring. The new route is concise, chromatography-free, and amenable
开发了一种高效,实用的带有噻唑并[5,4- d ]嘧啶核的TRPV1抑制剂的合成方法。修饰初始合成以促进5-氨基嘧啶的酰化和随后的噻唑形成。合成的特点是高效的两锅五步过程,用于构建噻唑并[5,4- d ]嘧啶环。新路线简洁明了,无需色谱法,适合大规模制备。

Certain TRPV1-modulating imidazolo-, oxazolo-, and thiazolopyrimdine compounds are described. The compounds may be used in pharmaceutical compositions and methods for treating disease states, disorders, and conditions mediated by TRPV1 activity, such as pain, arthritis, itch, cough, asthma, or inflammatory bowel disease.
