Procedure

To a solution of 59 mg (0.3 mmol) of 5-chloro-1H-indole-7-carboxylic acid and 96 mg of TBTU (0.3 mmol) in 3 ml DMF, were added 0.26 ml (1.5 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 91 mg (0.3 mmol) of (4-tert-butyl-benzyl)-[2-(4-chloro-phenyl)-ethyl]-amine in 2 ml DMF were added. After stirring for 2 h at rt, the reaction mixture was diluted with 50 ml water and extracted with 2×50 ml EtOAc. 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; EtOAc/heptane 1:9) to give 65 mg white solid (42%). MS (ISP) 479.4 (M+H)+.
