Participants

Reaction Steps

To a solution of 6-(4-((S)-1-((S)-6-(2-hydroxy-2-methylpropyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)phenyl)nicotinonitrile (120 mg, 0.26 mmol) in DMSO (8 mL) were added H2O2 (0.5 mL, 30%) and K2CO3 (35 mg, 0.26 mmol), and the mixture was stirred at rt for 3 h. The reaction was quenched with H2O (10 mL) and the mixture was extracted with EtOAc (4×20 mL). The organic layer was washed with brine, dried over Na2SO4 and concentrated to give the crude product, which was purified by preparative HPLC to give 6-(4-((S)-1-((S)-6-(2-hydroxy-2-methylpropyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)phenyl)nicotinamide (55.46 mg, 45%). LC-MS Method 2 tR=1.12 min, m/z=474, 416. 1H NMR (CDCl3): 1.03 (s, 3H), 1.09 (s, 3H), 1.46 (d, 3H), 2.13-2.26 (m, 5H), 2.30 (m, 1H), 2.44 (s, 1H), 2.79 (d, 1H), 5.61 (m, 1H), 6.15-6.38 (s, 1H), 6.97 (d, 2H), 7.13-7.29 (m, 5H), 7.60 (d, 2H), 7.70 (d, 2H), 8.15 (d, 1H), 9.05 (s, 1H).
