실험 절차

A solution of 10% lithium hydroxide monohydrate in water (2 mL) was added to a solution of (R)-3′-{2-[2-(3-chloro-phenyl)-2-hydroxy-ethylamino]-ethylamino}-biphenyl-3-carboxylic acid methyl ester (50 mg, 0.12 mmol, 1.00 equiv) in ethanol (4 mL). The solution was stirred at ambient temperature for about 16 hours, and then the pH value of the solution was adjusted to 7-8 with concentrated hydrogen chloride. After concentrating the solution in vacuo, the resulting crude residue was purified by prep-HPLC to give the title product of as a white solid (20 mg; yield=41.36%). LC-MS: m/z=411 (MH)+. Retention time: 1.69 minute. [α]20.4D −20° (c=0.075, MeOH). [a]=−20° (c=0.075 g/100 ml in methanol, T=20.4). 1H NMR (300 MHz, CD3OD) δ: 8.22 (s, 1H), 7.92 (d, J=7.8 Hz, 1H), 7.62 (d, J=7.8 Hz, 1H), 7.47 (s, 1H), 7.29-7.38 (m, 4H), 7.20 (t, J=8.1 Hz, 1H), 6.97 (m, 2H), 6.68 (d, J=1.5 Hz, 1H), 5.00 (m, 1H), 3.56 (t, J=6.0 Hz, 2H), 3.23-3.33 (m, 3H), 3.12 (m, 1H).
