Procedure

A foil covered flask charged with 2,2-dimethyl-3-((R)-3-((S)-1-(4-(1-methyl-6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)propanamide (20 mg, 0.04 mmol) in 1:1 CH3CN/H2O (1 mL) was treated with PhI(O2CCF3)2 (31 mg, 0.07 mmol). The reaction was complete after 24 h. The solvent was removed and the crude material purified by prep HPLC to afford (S)-6-(2-amino-2-methylpropyl)-3-((S)-1-(4-(1-methyl-6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-6-phenyl-1,3-oxazinan-2-one (16 mg). LC/MS ES+=460 (M+1). LC-MS Method 1 tR=1.06 min, m/z=460 (M+1); 1H NMR (CDCl3) 7.60 (dd, 1H, J=9 Hz, 2 Hz), 7.46 (d, 1H, J=3 Hz), 7.39-7.27 (m, 5H), 7.20 (d, 2H, J=7 Hz), 7.1 (d, 2H, J=8 Hz), 6.78 (d, 1H, J=9 Hz, 5.61 (q, 1H, J=7 Hz), 3.65 (s, 3H), 2.87 (m, 1H), 2.80 (d, 1H, J=16 Hz), 2.23 (d, 1H, J=16 Hz), 2.19-2.08 (m, 3H), 1.54 (d, 3H, J=7 Hz), 1.41 (s, 3H), 0.96 (s, 3H).
