本发明提供了一种3‑羟甲基‑9‑取代咔唑的制备方法。于干燥的100mL三口烧瓶中,冰盐浴冷却下依次加入A mL DMSO、B mol多聚甲醛、C mol乙醇钠、D mL无水乙醇,搅拌,固体溶解后,快速滴入E mol N‑烷基咔唑的DMSO溶液,A:E=(100~300):1,C:D=1:8,B:C:E=1:1.5:1,反应3 min后用几滴浓盐酸终止反应。然后加入蒸馏水,有固体析出,抽滤、水洗、干燥即得粗产品。粗品用无水乙醇重结晶得纯品3‑羟甲基‑9‑取代咔唑。本发明操作简单,反应时间短,产品纯度高,产率高,反应条件温和、安全环保,对该类化合物的合成及发展有重要意义。

Compounds represented by Structural Formula (I): where X is -H, -OR, -SH, -OC(O)R, -OC(O)OR,-OC(O)NRR or -SC(O)OR have anti-cystogenic activity, particularly against polycystic kidney disease. Such compounds can be used in pharmaceutical compounds and in methods of treating polycystic kidney diseases. The invention also includes novel 3-hydroxymethyl-substituted carbazoles and compounds of Structural Formula (I) where Ring A is a 5-, 6-, 7- or 8- membered non-aromatic carbocyclic ring optionally substituted at one or more substitutable ring atoms.
