Reaction Steps

To a solution of 30 mg (0.19 mmol) of 1H-indole-7-carboxylic acid and 60 mg of TBTU (0.19 mmol) in 6 ml DMF, were added 0.16 ml (0.93 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 85 mg (0.19 mmol) of [rac]-(4-tert-butyl-benzyl)-(3,3,3-trifluoro-2-hydroxy-propyl)-amine were added. After stirring for 4 h at rt, the reaction mixture was diluted with 60 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 (9 g silica gel; EtOAc/heptane 1:4) to give 17 mg white solid (17%). MS (EI) 418.2 (M)+.
