Reaction Steps

To a solution of 48 mg (0.3 mmol) of 1H-indole-7-carboxylic acid and 96 mg of TBTU (0.3 mmol) in 4 ml DMF, were added 0.26 ml (1.5 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 86 mg (0.3 mmol) (4-tert-butyl-benzyl)-[2-(3-fluoro-phenyl)-ethyl]-amine in 1 ml DMF was added. After stirring for 3 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 orange residue was purified by column chromatography (8 g silica gel; heptane/EtOAc 9:1) to give 112 mg (86%) of a yellow solid. MS (EI) 428.2 (M)+.
