Reaction Steps

To a solution of 3-chloro-4-fluorobenzonitrile (300 mg) and 1,1,1-trifluoro-2-propanol (263 mg) in THF (15 ml) was added 60% NaH (92.5 mg) at 5° C., followed by stirring at room temperature for 2 hours, addition of a saturated NH4Cl solution to complete the reaction, and extraction with EtOAc. The obtained organic layer was dried over anhydrous MgSO4, and concentrated. The residue was purified by silica gel chromatography (n-hexane:EtOAc=97:3 to 85:15) to obtain 3-chloro-4-(2,2,2-trifluoro-1-methylethoxy)benzonitrile (435 mg) as a colorless oily substance.
