Potassium Hydroxide → Potassium (4S)-3,5-dicyano-2-methyl-4-(3-methyl-1H-indazol-5-yl)-6-(trifluoromethyl)-4H-pyridin-1-ide

Participants

Reaction Steps

To a suspension of 60 mg (0.175 mmol) (4S)-2-methyl-4-(3-methyl-1H-indazol-5-yl)-6-(trifluoromethyl)-1,4-dihydropyridine-3,5-dicarbonitrile (Example 6) in THF (6 ml) under argon atmosphere was added 175 μl (0.175 mmol) 1 N aqueous potassium hydroxide solution, and the mixture was stirred under a weak argon stream for 5 days at room temperature. The resulting precipitate was dried in vacuo to yield 66 mg (100% of th.) of the title compound as a solid.
