HCID 21873804Tetrahydrofuran ethanolSolvent

Procedure

Hydrazine•monohydrate (0.124 ml) was added to an ethanol/tetrahydrofuran (5 ml/1 ml) solution containing (R)-2-chloro-6-((1-(1,3-dioxoisoindolin-2-yl)propan-2-yl)amino)-5-fluoronicotinonitrile (300 mg), followed by stirring at room temperature for 14 hours. Further, hydrazine•monohydrate (0.062 ml) was added, followed by stirring at room temperature for 8.5 hours. The solvent was distilled away under reduced pressure, chloroform was added, and insoluble matter was removed. Then, the solvent was distilled away under reduced pressure, and a yellow solid of (R)-6-((1-aminopropan-2-yl)amino)-2-chloro-5-fluoronicotinonitrile (38 mg) was thus obtained.
