実験手順
To a stirred solution of (S)-tert-butyl 2-(((benzyloxy)carbonyl)amino)-3-(4-(5-(4-(tert-butyl)phenyl)pyrimidin-2-yl)phenyl)propanoate INT-10 (757 mg, 1.34 mmol) in EA (100 ml) was added Pd/C (142 mg, 0.13 mmol) and the suspension degassed with H2. The mixture was stirred vigorously under an atmosphere of H2 overnight then filtered through celite and the filtrate was concentrated to give 532 mg (88%) of (S)-tert-butyl 2-amino-3-(4-(5-(4-(tert-butyl)phenyl)pyrimidin-2-yl)phenyl)propanoate INT-11. LCMS-ESI (m/z) calculated for C27H33N3O2: 431.3; found: 432.0 [M+H]+, tR=2.01 min (Method 4).
