Participants

Reaction Steps

A mixture of 1.15 g of 6,7-dichloro-2-ethyl-5-hydroxybenzo[b]thiophene, 0.87 g of ethyl bromoacetate, 0.4 g of potassium carbonate and 12 ml of dimethylformamide is stirred at 90° for 20 min. The cooled mixture is diluted with 100 g of ice water and the solid collected by filtration. Recrystallization of the crude product from pentane gives 1.3 g of ethyl [(6,7-dichloro-2-ethylbenzo[b]thien-5-yl)oxy]acetate as colorless prisms, mp 67°-68°.
