Reaction Steps

To a solution of 81 mg of 1H-indole-7-carboxylic acid (0.5 mmol) and 161 mg of TBTU (0.5 mmol) in 2 ml DMF, were added 0.43 ml (2.5 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 158 mg (0.5 mmol) [rac]-(4-tert-butyl-benzyl)-[2-(4-chloro-phenyl)-propyl]-amine in 3.5 ml DMF was added. After stirring for 22 h at rt, the reaction mixture was diluted with 50 ml water and extracted twice with 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 (40 g silica gel; heptane/EtOAc 2:1) to give 203 mg (86%) of a off-white solid. MS(ISP) 459.4 (M+H)+.
