Procedure

1,1-Dioxo-3-butyl-3-ethyl-5-phenyl-7-methoxy-8-ethoxycarbonylmethoxy-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 47; 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. AcOH (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 (400 MHz; CDCl3): 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).
