Reaktionsschritte
To 30 ml of chloroform were added 0.60 g of 1,2,3,4-tetrahydro-benzo[b]thieno[2,3-c]pyridine-3-carboxylic acid ethyl ester synthesized in Example 1, 0.64 ml of triethylamine, and 523 mg of 2-chlorobenzoyl chloride, and the mixture was stirred for one hour at room temperature. The reaction mixture was washed with ml of water and then with 30 ml of an aqueous sodium hydrogencarbonate solution having a pH of 9.0, and also with 30 ml of water. The chloroform layer was dried by sodium sulfate and the solvent was distilled off under reduced pressure to provide 614 mg (yield of 67%) of 2 -(2-chlorobenzoyl)-1,2,3,4-tetrahydro-benzo[b]thieno[2,3-c]pyridine-3-carboxylic acid ethyl ester.
