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).
