Versuchsvorschrift

To a solution of 9-oxo-6,7,8,9-tetrahydro-pyrido[1,2-a]indole-3-carboxylic acid (983 mg, 4.29 mmol) in anhydrous DMF (5 mL) was added HATU (4.00 g, 10.5 mmol), DMAP (3.00 g, 25.0 mmol) and pyridine-3-ylamine (1.00 g, 10.6 mmol). The reaction was stirred at 65° C. for 36 h. The reaction was poured into water and the resulting precipitate was filtered, washed with water and triturated with cold MeCN to give the title compound (256 mg, 20%) as an analytically pure as a brown powder; ESI-MS m/z 306 [M+H]+.
