実験手順

To a solution of 1,1-dioxo-3-butyl-3-ethyl-5-phenyl-7-bromo-8-(2-carboxyethoxy)-2,3,4,5-tetrahydro-1,5-benzothiazepine (Method 89; 70 mg, 0.134 mmol) and (R)-α-(t-butoxycarbonyl)benzylamine (J. Amer. Chem. Soc.; EN; 117; 44; 1995; 10879–10888; 35 mg, 0.169 mmol) in DCM (2.5 ml) was added 2,6-lutidine (29 mg, 0.268 mmol) and TBTU (56 mg, 0.174 mmol). The reaction mixture was stirred at room temperature for 2.5 hours, then diluted with DCM. The solution was washed with NaHCO3 (aq, sat), water, dried and the solvent was evaporated under reduced pressure. The residue was suspended in ether/petroleum ether and the crystals filtered to give the title compound 85 mg (89%). NMR (500 MHz) 0.79–0.86 (m, 6H), 1.04–1.28 (m, 4H), 1.35–1.56 (m, 11H), 1.60–1.77 (m, 2H), 2.82 (t, 2H), 3.13–3.25 (m, 2H), 3.72 (brs, 2H), 4.35–4.44 (m, 2H), 5.54 (d, 1H), 6.95 (d, 1H), 7.04 (t, 1H), 7.08 (d, 2H), 7.15 (s, 1H), 7.29–7.43 (m, 6H), 7.52 (s, 1H).
