is hydrogen or a suitable substituent and to intermediates for their preparation. The compounds prepared by the methods of the present invention are potent inhibitors of MAP kinases, preferably p38 kinase. They are useful in the treatment of inflammation, osteoarthritis, rheumatoid arthritis, cancer, reperfusion or ischemia in stroke or heart attack, autoimmune diseases and other disorders.
本发明涉及一种制备式I1中的三唑吡啶的新工艺,其中R1选自氢、(C1-C6)烷基或其他适当取代基组成的群体;R3选自氢、(C1-C6)烷基或其他适当取代基组成的群体;s是0-5的整数;R4是氢或适当的取代基,以及其制备的中间体。通过本发明的方法制备的化合物是MAP激酶,特别是p38激酶的有效抑制剂。它们在治疗炎症、骨关节炎、类风湿性关节炎、癌症、脑卒中或心脏病发作的再灌注或缺血、自身免疫性疾病和其他疾病方面有用。
