실험 절차

To a solution of 2-(S)-(3-dimethylaminomethylene-thioureidomethyl)-pyrrolidine-1-carboxylic acid 1,1-dimethylethyl ester (150 mg) in N,N-dimethylformamide (2 ml) was added 2-bromo-1-(2-ethylphenyl)-ethanone (109 mg). The mixture was stirred 65 h at room temperature, diluted with dichloromethane, washed twice with water, once with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (2:1 ethyl acetate/hexane eluant) to afford the product as yellow oil (129 mg, 65%).
