실험 절차

Boc-D-Proline (4.3 g, 20 mmol) was dissolved in DMF (100 ml). Then (S)-4-Chloro-α-methybenzylamine (3 ml, 22 mmol) and HBTU (7.58 g, 20 mmol), DIEA (6.96 ml, 40 mmol) were added while stirring. The reaction mixture was stirred overnight. The reaction mixture was diluted with EtOAc (100 ml), washed with 1N HCl (2×50 ml), sat. aq. NaHCO3 (2×50 ml) and brine, dried over Na2SO4, and concentrated in vacuo. The crude desired product as a white solid (6 g, 85.7%) directly used for next step.
