[EN] PROCESS FOR THE PREPARATION OF A CYP11A1 INHIBITOR AND INTERMEDIATES THEREOF [FR] PROCÉDÉ DE PRÉPARATION D'UN INHIBITEUR DE CYP11A1 ET DE SES INTERMÉDIAIRES
摘要:
The present invention relates to an improved process for the preparation of 4H-pyranone structured CYP11A1 inhibitors such as 5-((1-(methylsulfonyl)-piperidin-4-yl)methoxy)-2-((5-(trifluoromethyl)isoindolin-2-yl)methyl)-4H-pyran-4-one (1A) and key intermediates thereof including 5-(trifluoromethyl)isoindoline (V) and 5-hydroxy-2-((5-(trifluoromethyl)isoindolin-2-yl)methyl)-4H-pyran-4-one (III). CYP11A1 inhibitors are useful in the treatment of hormonally regulated cancers, such as prostate cancer and breast cancer.
