Procedure

To a solution of 0.040 g (0.19 mmol) 6-chloro-2-methyl-1H-indole-3-carboxylic acid, 0.069 ml (0.40 mmol) N,N-diisopropylethylamine and 0.061 g (0.19 mmol) 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate in 1 ml dry N,N-dimethylformamide were added 0.038 g (0.20 mmol) 4-(2-methoxy-phenyl)-piperidine at room temperature. After stirring for 1 h the reaction mixture was quenched with 0.5 M aqueous sodium hydroxide solution (20 ml) and extracted with ethyl acetate (2×30 ml). The combined organic layers were washed with water (2×30 ml) and brine (1×30 ml), dried over sodium sulfate and concentrated in vacuo. The residue was purified by flash chromatography (n-heptane/ethyl acetate) to give the title compound (0.050 g; 69%) as a white solid.
