実験手順
A solution of 3-amino-6-chlorobenzo[b]thiophene (5 g, 27 mmol) and 4-chloropyridine hydrochloride (6 g, 40 mmol) in 75 mL of 1-methyl-2-pyrrolidinone was stirred at 80° for 1.5 h, and then was cooled, stirred with water and extracted with ether. The aqueous layer was basified with sodium carbonate and extracted with ethyl acetate. The organic extract was washed with water and saturated sodium chloride solution and then was dried (anhydrous magnesium sulfate), filtered and concentrated to a dark oil. Elution through silica with ethyl acetate via flash column chromatography yielded 7 g of an amber oil. Conversion to the hydrochloride salt in 20% methanol in ether yielded 4.2 g of yellow crystals, mp 264°-266° (dec.).
