Procedure
1,1-Dioxo-3-butyl-3-ethyl-5-phenyl-7-methoxy-8-ethoxycarbonylmethoxy-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 7; 1.2 g) was dissolved in ethanol (20 ml). Sodium hydroxide (0.5) dissolved in H2O (1 ml) was added and the reaction mixture was warmed to 40° C. for 30 min. 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 1.1 g (97%) as a solid. NMR 0.75–0.85 (m, 3H), 0.9 (t, 3H), 1.0–1.7 (m, 8H), 3.2 (q, 2H), 3.65 (s, 3H), 3.65–3.85 (m, 2H), 4.7 (s, 2H), 6.4 (s, 1H), 7.0 (t, 1H), 7.1 (d, 2H), 7.3 (t, 2H), 7.5 (s, 1H).
