Reaction Steps

In a 250-ml capacity 3 neck flask (1.39 g) NaH suspended in 100 ml THF. At 0° C. IPA (4.36 g) in 20 ml THF added in this reaction flask. Allow it to stir at RT for 3 h. At 0° C. 2-chloro-6-trifluoromethylisonicotinonitrile (10 g) in 80 mL THF added in the flask in dropwise manner. Maintained 0° C. temperature for 30 min. Completion of reaction conformed by TLC. Reaction mixture was dumped in ice water. Extract compound in ethyl acetate. Organic layer was washed by water two times & dried over Na2SO4, filtered, and concentrated by rotary evaporation (40° C., 20 mmHg) to afford 8 g of yellow oil. The resulting crude compound forwarded for next step.
