Procedure
65 mg (0.23 mmol) of 9-chloro-1,2-dihydrothieno[3,2-f]quinoline-8-carbonitrile 3,3-dioxide are refluxed together with 39 mg (1.2 eq., 0.28 mmol) of 3-hydroxy-5-methoxyaniline in 2 ml of isopropanol for 2 hours. After the reaction is complete, the crude product is mixed with water and sat. ammonium chloride solution, extracted 3× with dichloromethane/methanol, washed 1× with sat. sodium chloride solution, dried over sodium sulphate and concentrated in vacuo. Final purification of the compound took place by chromatography. 20 mg (22%) of the desired product were obtained.
