실험 절차

In a dichloromethane solution containing 5.1 g of N-Boc-hydroxyproline (Boc-Hyp-OH), 0.35 g of tert-butylamine, 7.4 g of HOBt and 6.0 g of EDC hydrochloride were added under ice cooling and the resultant mixture was stirred overnight at room temperature. The reaction mixture was treated similarly to that in Example 144 (Process 2) to give 2.59 g of the title compound.
