Versuchsvorschrift

To a solution of 37 mg (0.17 mmol) 5-chloro-6-fluoro-1H-indole-7-carboxylic acid and 54 mg of TBTU (0.17 mmol) in 2 ml DMF, were added 0.148 ml (0.87 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 51 mg (0.17 mmol) (4-cyclopropyl-benzyl)-[2-(3-trifluoromethyl-phenyl)-ethyl]-amine in 1 ml DMF was added. After stirring for 17 h at rt, the reaction mixture was diluted with 30 ml water and extracted with EtOAc (2×). The combined organic phases were washed with water and brine, dried with magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (8 g silica gel; diethylether/heptane 1:1; then 8 g silicagel DCM/heptane 70:30 to 90:10) to give 43 mg white foam (48%). MS (EI) 514.1 (M)+.
