Route of Synthesis
| With trifluoroacetic acid In dichloromethane for 3.5h | 91% |
| With trifluoroacetic acid In dichloromethane for 0.75h Ambient temperature | 84% |
| With trifluoroacetic acid In dichloromethane at 20℃ for 1h Experimental Procedure General procedure: Fmoc-Asp(t-Bu)-OBn (SI-4, 1.19 g, 2.38 mmol)was dissolved in TFA/CH2Cl2 (1.8 mL/18 mL), and stirred at room temperature (1 h). The mixture was concentrated to provide crude SI-5. A solution of this material (0.32 g, 0.73 mmol), HATU (0.33 g, 0.88 mmol), HOBt (0.12 g, 0.88 mmol) and DIPEA (0.38 mL, 2.19 mmol) in CH2Cl2 (7.5 mL) was stirred at 0 °C under nitrogen (0.5 h), then a solution of amine SI-6 (0.18 g, 0.88 mmol) dissolved in CH2Cl2 (3.0 mL) was added and the the mixture was stirred at room SI-6 temperature (overnight). The reaction was quenched by the addition of H2O and the organic layer was separated and aqueous layer was extracted (EtOAc). The combined organic layer was washed with aqueous 1N HCl, H2O, aqueous NaHCO3, brine and dried (MgSO4). The mixture was filtered and concentrated and the residue was purified by silica gel column chromatography (EtOAc/petroleum etherfrom 1:4 to 1:2) to afford SI-7 as a white semi-solid (0.27g, 60%). |
