실험 절차

To a stirring solution of #114 (1.02 g, 1.61 mmol, 1.0 eq.) and 1-(tert-butoxycarbonyl)-2-methyl-L-proline (443 mg, 1.93 mmol, 1.2 eq.) in 12 mL of dichloromethane, HATU (735 mg, 1.93 mmol, 1.2 eq.) was added followed by Hunig's base (1.12 mL, 6.45 mmol, 4.0 eq.). The reaction was allowed to stir at room temperature for 2 hours. The reaction was reduced down, diluted with ethyl acetate before being washed with 0.5 N HCl and brine. Organics where then dried over sodium sulfate, reduced to a smaller volume, and then reduced down on silica. Silica chromatography was then performed (Gradient: 0%-45% acetone in heptanes) producing #116 (1.02 g, 74%) as a white solid. LC-MS (Protocol Q): m/z 844.3
