実験手順

3-geranyloxy-4-methoxybenzoic acid(1.52 g) was dissolved in chloroform (50 ml) and triethylamine (1.4 ml), and then diphenylphosphinic chloride(1.0 ml) was added thereto while being cooled with ice. After being stirred for 15 minutes, the mixture, with 2-aminomethyl-1-ethylpyrrolidine(0.7 ml) added thereto, was stirred for 1.5 hours at room temperature. The reaction mixture was washed with saturated sodium hydrogencarbonate aqueous solution and saturated brine successively, dried over sodium sulfate anhydride, and then concentrated under a vacuum. The residue was purified by silica gel column chromatography (chloroform:methanol=15:1), thereby yielding 1.47 g(71%) of the aimed compound.
