실험 절차

To a solution of 951 mg (4.86 mmol) of 5-chloro-1H-indole-7-carboxylic acid and 1.997 g (5.35 mmol) [2-(3-benzyloxy-phenyl)-ethyl]-(4-tert-butyl-benzyl)-amine in 50 ml DMF, were added 1.6 ml (14.58 mmol) N-methylmorpholine and 2.77 g TBTU (7.29 mmol) at rt. After stirring for 16 h at rt, the reaction mixture was diluted with 300 ml water and extracted with EtOAc (2×). The combined organic phases were washed with twice 200 ml water and 100 ml brine, dried with magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (90 g silica gel; heptane/EtOAc 9:1 then 4:1) to give 2.41 g of 5-chloro-1H-indole-7-carboxylic acid [2-(3-benzyloxy-phenyl)-ethyl]-(4-tert-butyl-benzyl)-amide as a light yellow solid (88%). MS (ISP) 551.3 (M+H)+.
