実験手順
To a solution of 77 mg (0.20 mmol) {2-[(5-Hydroxy-benzo[b]thiophene-2-carbonyl)-amino]-phenyl}-carbamic acid tert-butyl ester (4) in 3 ml ethyl acetate was added 120 mg potassium carbonate and 36 mg (0.25 mmol) (2-chloro-ethyl)-dimethyl-amine hydrochloride. The reaction mixture was heated at reflux for 16 h and poured into brine. The aqueous phase was extracted with ethyl acetate and the organic phase was dried over sodium sulfate, the solvent was evaporated and the residue subjected to silica gel chromatography (dichloromethane/methanol 19:1 and then 9:1). (2-{[5-(2-Dimethylamino-ethoxy)-benzo[b]thiophene-2-carbonyl]-amino}-phenyl)-carbamic acid tert-butyl ester (5) (72 mg, 0.158 mmol) was obtained as a colorless solid.
