실험 절차

1-[4-(4-Oxo-2-thioxo-thiazolidin-5-ylidenemethyl)-phenyl]-piperidin-4-one (which was obtained in Example 34) (0.16 g, 0.5 mmol) and (2S)-1-amino-3-phenoxy-propan-2-ol (which was obtained in Example 3) (0.12 g, 0.75 mmol) were mixed in 1,2-dichloroethane (10 mL) and then treated with sodium triacetoxyborohydride (0.16 g, 0.75 mmol) and acetic acid (0.045 g, 0.75 mmol). After stirring at room temperature under a nitrogen atmosphere for one day the mixture was quenched with 1N sodium hydroxide (NaOH) and then poured into a saturated aqueous sodium bicarbonate (NaHCO3). The aqueous layer was extracted with dichloromethane and the combined organic layers were dried and concentrated. The residue was purified by preparative thin layer chromatography (16% MeOH/CH2CH2) to give the title compound as a pale yellowish solid; mp>220° C. (decomposed); 1H NMR (300 MHz, DMSO-d6) δ 1.50–1.70 (m, 2 H), 1.90–2.10 (m, 2 H), 2.60–3.40 (m, 7 H), 3.90–4.20 (m, 3 H), 6.70–7.15 (m, 6 H), 7.30 (d, J=8.8 Hz, 2 H); 7.38 (d, J=8.8 Hz, 2 H); MS (ES) m/z: 470.0 (MH+); HRMS Calcd. for C24H27N3O3S2(M+): 469.1494. Found: 469.1488.
