실험 절차

Boc-Leu-Ala-OBzl was prepared by the procedure for dipeptide synthesis in Example 2. Boc-Leu-Ala-OBzl (23.7 g, 57.7 mmoles) was dissolved in 40 mL of anhydrous trifluoroacetic acid. After 15 min, excess trifluoroacetic acid was removed by evaporation and the residue was treated with ether to yield H-Leu-Ala-OBzl.trifluoroacetic acid as a crystalline product (22.8 g).
