Procedure

2,2-dimethyl-3-((R)-2-oxo-3-((S)-1-(4-(6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-6-phenyl-1,3-oxazinan-6-yl)propanenitrile (6 mg, 0.013 mmol) was dissolved in DMF (2.5 mL). Cs2CO3 (c.a. 15 mg, excess) and i-PrI (100 μL, excess) were added. The mixture was stirred for 3 h at rt. LC-MS found the reaction was complete. The mixture was purified by prep HPLC to afford 3-((R)-3-((S)-1-(4-(1-isopropyl-6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)-2,2-dimethylpropanenitrile (1.99 mg, 30%). LC-MS Method 1 tR=2.03 min, m/z=498; 1H NMR (CDCl3) 8.35 (d, 1H), 7.80 (dd, 1H), 7.37 (m, 5H), 7.22 (d, 2H), 6.92 (d, 2H), 6.83 (d, 1H), 5.66 (q, 1H), 5.22 (m, 1H), 2.93 (m, 1H), 2.16 (s, 2H), 1.55 (d, 3H), 1.46 (s, 3H), 1.40 (d, 6H), 1.33 (s, 3H).
