Reaction Steps

A solution of n-butyl lithium (22.3 ml. of 1.6 M solution in hexane) was added dropwise to a stirred solution of 2,3-dibromo-6-methylbenzo[b]thiophene (11.76 g.) in dry ether (150 ml.) at 0° under an atmosphere of dry nitrogen. The resulting solution was stirred at 0° for 1 hour and then water (50 ml.) was added. The mixture was stirred for a few minutes and then the ether layer was separated, dried (Na2SO4) and evaporated to give an oil. The oil was distilled to give 3-bromo-6-methylbenzo[b]thiophene (5.80 g.), b.p. 112°-114° C. @ 0.2 m.m., m.p. 51°-53° C. (from methanol).
