实验过程

The title compound was prepared using a similar procedure as described in Example 1, Step 8, starting from (S)-2-amino-3-[4-(1,3,6-trimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)phenyl]propionic acid propyl ester (10.78 g, 30 mmol), 1-[4-azidobutyl]cyclopentanecarboxylic acid (8.24 g, 39 mmol), HBTU (14.79 g, 39 mmol), and DIPEA (11.63 g, 15.68 mL, 90 mmol), and after ISCO column chromatography purification, resulted in an amorphous off-white solid (14.1 g, 85%). ES(+)-HRMS m/e calcd. for C29H40N6O5 (M+H)+ 553.3133, obsd. 553.3133.
