실험 절차

A mixture of 1.08 mmol of 3,5-di-iso-propyl-2-n-propoxy phenylboronic acid, 1.62 mmol of 2-formyl-4-iodo-benzo[b]thiophene and 62 mg (0.05 mmol) of Pd(PPh3)4, 1 mL of 2N aqueous sodium carbonate in 9 mL of toluene and 4 mL ethanol was heated to reflux. After complexion (TLC), water was added and the solution was extracted with ethyl acetate. The organic layer is dried over MgSO4 and after evaporation of the solvents, the crude oil was purified over a short silica plug (eluent: 10/90=ethyl acetate/hexane) to afford 2-formyl-4-(2-n-propoxy-3,5-di-iso-propylphenyl)-benzo[b]thiophene.
