Procedure

To a solution of 100 mg (0.47 mmol) 5-chloro-6-fluoro-1H-indole-7-carboxylic acid and 150 mg of TBTU (0.47 mmol) in 7 ml DMF, were added 0.4 ml (2.34 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 141 mg (0.47 mmol) (4-tert-butyl-benzyl)-[2-(4-chloro-phenyl)-ethyl]-amine in 1 ml DMF was added. After stirring for 17 h at rt, the reaction mixture was diluted with 80 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 112 mg off-white foam (47%). MS (EI) 496.1 (M)+.
