Procedure

The mixture of 310 mg of 1-(5-chloro-4-nitrothiophene-2-sulfonyl)piperidine, 250 mg of piperidine-4-carboxylic acid and 3 ml of NMP is stirred at 85° C. for 1 h, cooled, diluted with 15 ml of water and stirred. The precipitate is filtered off with suction, washed with water and recrystallized from isopropanol/water (4:1).
