실험 절차

To a stirring solution of #121 (0.55 g, 1.0 mmol, 1.0 eq.) in 10 mL of dichloromethane and 1 mL of DMF, #32 (0.62 g, 1.0 mmol, 1.0 eq.) was added followed by HATU (0.42 g, 1.1 mmol, 1.1 eq.) and Hunig's base (0.72 mL, 4.1 mmol, 4.0 eq.). The reaction was allowed to stir at room temperature for approximately 21 hours. Reaction was reduced down, diluted with ethyl acetate, and then washed with 0.5 N HCl and brine. Organic layer was dried over sodium sulfate, filtered, and concentrated to a smaller volume before being concentrated down onto silica. Silica chromatography was then performed (Gradient: 0%-40% acetone in heptane) producing #122 (0.62 g, 62%) as a white solid. LC-MS (Protocol Q): m/z 982.3 [M+H+] retention time=2.44 minutes.
