실험 절차

N-[2-(2-Methoxyphenyl)ethyl]heptan-1-amine (0.091 g, 0.366 mmol) was dissolved in DMF (5 ml), (4-{[2-(methoxycarbonyl)benzyl]oxy}phenyl)acetic acid (0.100 g, 0.333 mmol) was added and the mixture was cooled to 0° C. N-[(1H-1,2,3-Benzotriazol-1-yloxy)(dimethylamino)methylene]-N-methylmethanaminium tetrafluoroborate (0.118 g, 0.366 mmol) and N-ethyl-N,N-diisopropylamine (0.090 g, 0.699 mmol) were added. The solution was stirred overnight at room temperature. EtOAc (20 ml) was added and the organic phase was washed with two portions of water (2×20 ml). The organic layer was dried (MgSO4) and the solvent was removed by evaporation. The crude was purified by preparative HPLC (started with isocratic acetonitrile/buffer 60/40 and then the acetonitrile concentration was increased to 100%, the buffer was a mixture of acetonitrile/water 10/90 and ammonium acetate (0.1 M, column KR-100-7-C8, 50 mm×250 mm, flow 40 ml/min). The product containing fractions were pooled and the acetonitrile was removed by evaporation. EtOAc (10 ml) was added and the organic phase was washed with two portions of brine and dried (MgSO4) and the solvent was removed by evaporation to give 0.094 g of methyl 2-{[4-(2-{heptyl[2-(2-methoxyphenyl)ethyl]amino}-2-oxoethyl)phenoxy]methyl}benzoate (yield 53.1%).
