７Ｈ−ピロロ［２，３−ｄ］ピリミジン誘導体の製造方法及びその合成中間体
Document Type and Number:
Japanese Patent JP6434678
Kind Code:
B2
Abstract:
The present invention provides processes for preparing 7H-pyrrolo[2,3-d]pyrimidine derivatives, which are useful as a Janus kinase (JAK) inhibitor, intermediates thereof, and processes for preparing the intermediates. The present invention provides processes for preparing 3-[(3S,4R)-3-methyl-6-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1,6-diazaspiro[3.4]octan-1-yl]-3-oxopropanenitrile using salts of (3S,4R)-1-benzyl-3-methyl-1,6-diazaspiro[3.4]octane with organic acids.
