摘要 |
The invention provides new processes such as enzymatic reduction with a ketoreductase enzyme or an alcohol dehydrogenase enzyme for making and purifying salts of hydroxylated cyclopentapyrimidine compounds, which are useful as AKT inhibitors used in the treatment of diseases such as cancer, including the monohydrochloride salt of (S)-2-(4-chlorophenyl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(isopropylamino)propan-1-one. |
