Dimethylformamide → HCID 12343242, compound

Participants

Reaction Steps

To a stirred and cooled (ice-bath) solution of 27 parts of 4-fluorobenzeneacetonitrile in 180 parts of N,N-dimethylformamide are added 6.2 parts of sodium hydride dispersion 78% and the whole is stirred for 1 hour while cooling. Then there are added dropwise 31 parts of 1-bromopentane. Upon completion, stirring is continued for 2 hours at room temperature. The reaction mixture is poured onto 1000 parts of water and the product is extracted twice with 2,2'-oxybispropane. The combined extracts are washed three times with water, dried, filtered and evaporated. The residue is distilled, yielding 21 parts of 4-fluoro-α-pentylbenzeneacetonitrile; bp. 85°-93° C at 0.1 mm. pressure.
