実験手順

A mixture of 5-chloro-2-pentanone ethylene ketal (0.54 g), (2R)-1-[3,5-bis(trifluoro-methyl)benzoyl]-2-(1H-indol-3-ylmethyl)piperazine (1.37 g), diisopropylethylamine (0.6 mL), and dimethylformamide (25 mL) was heated overnight, at 90°C. After cooling to room temperature the mixture was poured in water and extracted with ethyl acetate. The organic layer was dried (Na2SO4), and concentrated in vacuo. The residue was purified by flash chromatography (SiO2, CH2Cl2/MeOH 95/15) to afford (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(1H-indol-3-ylmethyl)-4-[3-(2-methyl-1,3-dioxolan-2-yl)propyl]piperazine (0.7 g, 40%). MH+ 584.
