実験手順

The N-(3-sulfo-propyl)-phenylalanine ethyl ester (DM-258-069, 860 mg, 2.7 mmol) was dissolved in 2N NaOH (1.2 g of NaOH and 15 mL of water). The reaction was stirred at room temperature overnight. Dowex Marathon C ion exchange resin (strongly acidic) was added to the solution. The suspension was stirred for 15 minutes before the resin was removed by filtration. The filtrate was evaporated under reduced pressure and lyophilized, affording the title compound (654 mg, 84%). 1H NMR (D2O, 500 MHz) δ ppm 7.20 (m, 5H), 3.96 (t, 1H, J=6.3 Hz), 3.11 (m, 4H), 2.80 (t, 2H, J=7.3 Hz), 1.95 (m, 2H). 13C (D2O, 125 MHz) δ ppm 171.46, 134.03, 129.50, 129.28, 128.10, 62.02, 47.97, 45.64, 35.23, 21.39. [α]D=+14.9° (c=0.0013 in water), ES-MS 286 (M−1).
