実験手順

To a suspension of potassium hydride (0.303 g, 2.64 mmol, 35% in oil) in anhydrous THF (5.0 mL) was added the (±)-6-(1-naphthyl)pyrrolo[2,1-d][1,5]benzothiazepin-7(6H)-one (0.9 g, 2.64 mmol) dissolved in anhydrous THF (7 mL). The reaction mixture was stirred at rt for 2 h, and then acetyl chloride (0.239 g, 3.04 mmol) was slowly added. After stirring for 12 h at rt, the solvent was removed in vacuo and the residue was dissolved in chloroform. The organic layer was washed with brine, dried and concentrated. The residue was chromatographed (dichloromethane and hexane 1:1) to give the PBOX-9 in 86% yield. IR (neat) 1762 cm−1; 1HNMR (CDCl3) δ 1.70 (s, 3 H) 6.45 (m, 1 H), 6.63 (m, 1 H), 7.19-7.55 (m, 10 H), 7.78-7.87 (m, 2 H).
