실험 절차

A mixture of 3-methylbenzo[b]thiophene-6-carboxylic acid methyl ester (1.03 g), N-bromosuccinimide (0.89 g), azobisisobutyronitrile (0.2 g) and carbon tetrachloride (25 ml) was heated under reflux for 2 hours and then cooled. The mixture was diluted with a few ml. of chloroform, washed with water, dried (Na2SO4) and evaporated to give a solid which was crystallized from ethyl acetate/petrol (b.p. 60°-80° C. to give 3-bromomethylbenzo[b]thiophene-6-carboxylic acid methyl ester (0.80 g), m.p. 108°-110° C.
