실험 절차
A solution of 7.411 g of 5-methylbenzo[b]thiophene (Maybridge, Chemical Co. Ltd., 11-78) in 35 ml of ether is added dropwise at 0° to a mixture of 40 ml of 1.5N butyllithium in hexane and 40 ml of ether. After 30 minutes, a solution of 9.963 g of trimethyltin chloride in 50 ml of ether is also added dropwise at 0°. After stirring for 1 hour at 0°, 50 ml of 5% ammonium chloride solution are added. The product is obtained by extracting with 100 ml and 150 ml of ether. Distillation at 0.15 mbar and 100°-106° yields 5-methyl-2-trimethylstannylbenzo[b]thiophene.
