실험 절차

1,1-Dioxo-3-butyl-3-ethyl-5-phenyl-7-bromo-8-ethoxycarbonylmethoxy-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 8; 0.34 g) and sodium hydroxide (0.3 g) were dissolved in ethanol and the mixture was heated to reflux for 1 hour. Acetic acid (1 ml) was added and the solvent was removed at reduced pressure. The residue was partitioned between DCM/H2O and the organic layer was separated and dried. Trituration of the residue with n-hexane gave the title compound 0.29 g (90%) as a solid. NMR (500 MHz) 0.7–0.8 (m, 6H), 1.0–1.7 (m, 8H), 3.1–3.2 (m, 2H), 3.6 (brs, 2H), 4.6 (s, 2H), 6.9–7.1 (m, 4H), 7.2 (m, 2H), 7.5 (s, 1H).
