PROCEDURE
实验过程
Boc-Leu-Leu-Lys(Z)-Leu-Leu-OMe (SEQ. ID No. 2) (18.2 g, 21.5 mmol) was added to a solution of HCl gas (31.0 g, 850 mmol) in MeOH (360 g) and cooled to 5° C. The reaction mixture was stirred, allowed to warm up to room temperature and stirring was continued for 4.5 h. The reaction mixture was cooled to 0° C., poured into ice/H2O (630 g) and stirred for 1 h. The white solid was collected by filtration, washed with distilled water (500 mL) and air dried. Yield of product: 14.8 g, 87.6%; HPLC area % purity: 99.2%.
