Reaction Steps

Lithium hydroxide (0.062 g) was added to a solution of 1,1-dioxo-3,3-dibutyl-5-phenyl-7-methoxy-8-ethoxycarbonylmethoxy-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 5; 0.448 g, 0.865 mmol) in THF/H2O (2/1, 6 ml) After 1 hour AcOH (0.5 ml) was added and most of the solvent was removed under reduced pressure. The crude product was purified by HPLC (MeCN) to give the title compound 0.408 g (96%) as a white solid. NMR (CD3OD) 0.75–0.85 (m, 6H), 1.00–1.30 (m, 8H), 1.35–1.55 (m, 4H), 3.20 (s, 2H), 3.65 (s, 3H), 3.70 (brs, 2H), 4.50 (s, 2H), 6.50 (s, 1H), 6.90–7.30 (m, 5H), 7.40 (s, 1H).
