To a solution of 48 mg (0.3 mmol) 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, 96 mg (0.3 mmol) of (4-tert-butyl-benzyl)-[2-(3-chloro-4-fluoro-phenyl)-ethyl]-amine in 2 ml DMF were 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 to give 141 mg white solid (99%). MS (ISP) 463.4 (M+H)+.
