Procedure

To a solution of 100 mg (0.47 mmol) of 5-chloro-6-fluoro-1H-indole-7-carboxylic acid and 150 mg of TBTU (0.47 mmol) in 10 ml DMF, were added 0.4 ml (2.34 mmol) of N,N-diisopropylethyl amine. After stirring for 5 min at rt, 156 mg (0.47 mmol) of (4-tert-butyl-benzyl)-[2-(3-difluoromethoxy-phenyl)-ethyl]-amine were added. After stirring for 22 h at rt, the reaction mixture was diluted with 10 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 two successive column chromatographies (8 g silica gel; EtOAc/heptane 1:3; then again 8 g silica gel; and DCM/heptane 70:30 to 90:10) to give 91 mg white solid (27%). MS(ISP) 528.3 (M+H)+.
