실험 절차

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU--1.46 ml, 9.5 mmol) was added to a mixture of ethyl 3-chloro-6-(3-pyridylmethoxy)benzo[b]thiophene-2-carboxylate (Preparation 4, 3.0 g, 8.6 mmol) and thiophenol (1.76 ml, 17.2 mmol) in dimethylformamide (15 ml) under a nitrogen atmosphere. The solution was heated to 60° C. for 5 hours and then partitioned between diethyl ether and water. The organics were separated and washed with water, dried (magnesium sulfate) and evaporated under reduced pressure. The residue was flash chromatographed on silica gel using diethyl ether, and then ethyl acetate, as eluant. The isolated product was crystallised from diethyl ether and hexane to give the title compound as a colourless solid (2.85 g).
