To a solution of 0.031 g (0.080 mmol) 1′-[(6-chloro-2-methyl-1H-indol-3-yl)carbonyl]-3H-spiro[2-benzofuran-1,4′-piperidine] (5) in 1 ml dry N,N-dimethylformamide were added 0.004 g (0.08 mmol) sodium hydride (50% in oil). After stirring for 20 min 0.015 ml (0.08 mmol) 3,5-bis(trifluoromethyl)benzyl bromide were added. After stirring for 16 h the reaction mixture was quenched with water and extracted with ethyl acetate (2×50 ml). The combined organic layers were washed with water (2×30 ml) and brine (1×30), dried over sodium sulfate and concentrated in vacuo. The residue was purified by flash chromatography (n-heptane/ethyl acetate) to give the title compound (0.020 g; 41%) as a white solid. MS m/e (%): 607 (M+H+, 100).
