86% | Compound 7 (0.337 g, 1.0 mmol), HOBT (0.135 g, 1.0 mmol) and DCC (0.206 g, 1.0 mmol), were dissolved in DMF (5 ml) and stirred at 25° C. for 1 h. Compound 4 (1.134 g, 1.0 mmol) was added and the stirring was continued for 24 h at 25° C. Then, the precipitate was filtered and the DMF was removed by evaporation under reduced pressure. The residue was triturated with hot acetone (100 ml), and the precipitate was filtered and dried under vacuum. The product was recrystallized from hot water yielding 1.25 g (86percent yield) of 6 as a white crystalline solid. TLC analysis of 6 performed on silica plates (EtOAc:2-propanol:conc. NH4OH:water-7:7:5:4) showed one major spot (Rf=0.56). 1H NMR (DMSO-d6) delta: 1.35 (s, 9H), 1.6-2.2 (m, 4H), 3.30-3.65 (m, 42H), 4.45 (m, 6H), 4.85 (m, 7H), 5.1 (s, 2H), 5.62-5.78 (m, 14H), 7.35 (s, 5H). HPLC (Luna 5u NH2 100 A, size 250-4.6 mm, mobile phase 65percent acetonitrile-35percent H2O, flow 1.2 ml/min), Rt=5.8 min. | |
