Upon disappearance of the deep blue color 25 g of thinly shaven strips of sodium was added. After 30 mins of stirring at −78° C., 50 g of 2,5-dichloroanisole was added as a solution in hexane (70 mL) dropwise and the reaction warmed to −45° C. for 2 hrs. Upon completion the ammonia was allowed to evaporate. The crude pot was then diluted in chloroform and 100 g of NH4Cl was added slowly. The combines were taken up in a separatory funnel and washed with water (3×) followed by brine (1×). The organic layer was dried over sodium sulfate and concentrated in vacuo. The resulting solid can be used without further purification. Yield: 99%.
