실험 절차

Sodium hydroxide (0.045 g, 1.13 mmol) was added to a solution of 1,1-dioxo-3-butyl-3-ethyl-5-phenyl-7-bromo-8-[1-(ethoxycarbonyl)ethoxy]-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 1; 0.050 g, 0.090 mmol) in EtOH (4 ml, 95%) and heated under reflux. After 1.5 hours AcOH (0.2 ml) was added and most of the solvent was removed under reduced pressure. The crude product was extracted (DCM/H2O), dried (MgSO4) and evaporated to give the title compound 0.031 g (65%) as white solid. NMR (500 MHz, CD3OD) 0.70–0.85 (m, 6H), 0.95–1.25 (m, 4H), 1.35–1.70 (m, 4H), 2.65 (d, 3H), 3.10–3.35 (m, 2H), 3.45–3.95 (m, 2H), 4.70 (q, 1H), 6.90–7.35 (m, 6H), 7.45 (s, 1H).
