実験手順

In a 300 ml three neck flask fitted with a mechanical stirrer, thermometer and addition funnel was added 20.8 gm (0.1 mol) of (p-chlorophenyl)hexanenitrile, 34.8 gm (0.2 mol) of methylene bromide and 50 ml of DMSO. To the reaction flask was added 24 ml of 50% (w/w) sodium hydroxide, dropwise over a 35 minute period. Upon completion of the reaction, it was quenched by adding 500 ml of water. The aqueous mixture was extracted three times with ether, then the combined ether extracts were washed three times with water and once with brine. The organic phase was dried over sodium sulfate, filtered and the solvent removed by rotary evaporation yielding 22.6 gm of a yellow oil.
