Versuchsvorschrift

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 (3.95 g, 11 mmol), 2,6-dichloro-4-triisopropylsilanyloxy-benzoic acid (3.63 g, 10 mmol), HBTU (5.42 g, 14.3 mmol), and DIPEA (4.26 g, 5.75 mL, 33.0 mmol), and after ISCO column chromatography purification, resulted in an amorphous white solid (1.7 g, 24%). ES(+)-HRMS m/e calcd. for C35H47Cl2N3O6Si (M+H)+ 704.2684, obsd. 704.2683.
