Reaction Steps

To a solution of 1,3-dibromo-2-chlorobenzene (3.4 g, 12.6 mmol) in dry diethyl ether (60 ml), under nitrogen, at −78° C., was added dropwise n-butyllithium (2.5 M in hexane, 5.0 ml, 12.6 mmol). The mixture was stirred for 1 h after which dimethyldisulfide (1.0 ml, 13.9 mmol) was added dropwise. The resulting mixture was stirred at −78° C. for 30 min and then brought to ambient temperature. Water (100 ml) was added and the mixture was extracted with ethylacetate (3×100 ml). The combined organic phases was dried (MgSO4), filtered and evaporated to dryness.
