The present invention is related to processes for preparing chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines of Formula III, and related synthetic intermediate compounds. The chiral substituted pyrazolyl pyrrolo[2,3-d]pyrimidines are useful as inhibitors of the Janus Kinase family of protein tyrosine kinases (JAKs) for treatment of inflammatory diseases, myeloproliferative disorders, and other diseases.

NMR spectroscopy. The catalytic 1,2-migration of a trimethylsilyl group in 4-halo-N-trimethylsilylpyrazoles was detected. Silylotropy inN-trimethylsilylpyrazoles in the presence of halogens of trimethylhalosilanes is believed to proceed through formation ofN,N′-bis(trimethylsilyl)pyrazolium salts, the barrier of silylotropy in pyrazoles being markedly reduced.
通过动态 1 H、13 C 和 29 Si NMR 光谱研究了 4-取代的 N-三甲基甲硅烷基吡唑中的甲硅烷基向性。检测到 4-卤代-N-三甲基甲硅烷基吡唑中三甲基甲硅烷基的催化 1,2-迁移。在三甲基卤代硅烷的卤素存在下,N-三甲基甲硅烷基吡唑中的甲硅烷基化被认为是通过形成 N,N'-双(三甲基甲硅烷基)吡唑鎓盐进行的,吡唑中甲硅烷基化的屏障显着降低。
