実験手順

800 mg (3.17 mmol) N-[2-(3,4-Dimethoxyphenyl)ethyl]-N-methyl-1,3-propanediamine (D2), 630 mg (3.33 mmol) 4-nitro benzoyl chloride and 0.35 g (3.49 mmol) triethylamine in 30 ml methylene chloride were stirred for 2 hours at room temperature. The mixture was washed with water, dried over MgSO4 and concentrated in vacuo. The residue was purified twice by chromatography on silicagel using methylene chloride/methanol: 97/3 then 94/6 yielding 700 mg (55%) of the desired compound as a base. The compound was salified in methylene chloride by adding a solution of hydrochoric acid in diethyl ether yielding 594 mg (43%) of the desired compound as a yellow solid: mp=80-90° C.
