Prepared using General Procedure 8: To a stirred solution of (S)-tert-butyl 2-(((benzyloxy)carbonyl)amino)-3-(4-(5-bromopyrimidin-2-yl)phenyl)propanoate (1.08 g, 2.11 mmol) INT-7 in DCM (10 mL) was added TFA (5 mL). After 16 h the mixture was diluted with toluene (10 mL) and evaporated. Further toluene (2×10 mL) was evaporated from the residue to afford 962 mg (100%) of (S)-2-(((benzyloxy)carbonyl)amino)-3-(4-(5-bromopyrimidin-2-yl)phenyl)propanoic acid as an off-white solid. LCMS-ESI (m/z) calculated for C21H18BrN3O4: 455.1. found 456.0 [M+H]+, tR=5.81 min (Method 10).
