Participants

Reaction Steps

Thionyl chloride (2.0 ml) was added dropwise to a stirred solution of 6-bromo-2-hydroxymethyl-3-methylbenzo[b]thiophene (3.60 g) and pyridine (3 drops) in chloroform (80 ml). The solution was stirred at room temperature for 1 hour, then washed with water, sodium bicarbonate solution and dried (Na2SO4). Evaporation of the solvent gave a quantitative yield of 6-bromo-2-chloromethyl-3-methylbenzo[b]thiophene. A sample crystallised from petrol (b.p. 40°-60°) had m.p. 92°-93°.
