実験手順

A mixture of 2-chloroethanal O-[2-(morpholin-4-yl)ethyl]oxime (0.13 g), (2R)-1-[3,5-bis(trifluoromethyl)-benzoyl]-2-(1H-indol-3-ylmethyl)piperazine (0.29 g), diisopropylethylamine (0.11 mL), and acetonitrile (10 mL) was heated under reflux overnight. After cooling to room temperature the solvent was removed in vacuo, and the residue treated with dichloromethane and K2CO3 (aq). The layers were separated, the organic layer was dried (Na2SO4), and concentrated in vacuo. The residue was purified by flash chromatography (SiO2, CH2Cl2/MeOH/NH4OH 92/7.5/0.5) to afford 2-{(2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(1H-indol-3-ylmethyl)-piperazin-4-yl}-ethanal O-[2-(morpholin-4-yl)ethyl]oxime 0.38 g (95%) as an E/Z mixture. MH+ 626, Rf 0.53+0.66 (E+Z isomer) (CH2Cl2/MeOH/NH4OH 92/7.5/0.5).
