実験手順

To a suspension of NaH (330 mg, 8.24 mmol) in THF (20 mL) was added a solution of (R)-6-allyl-6-(4-fluorophenyl)-3-((S)-1-(4-(6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-1,3-oxazinan-2-one (891 mg, 0.174 mmol) in THF (30 mL) at 0° C., and the resulting mixture was stirred for 1 h. CH3I (2 ml) was added and the mixture was stirred overnight. The reaction was quenched by aqueous NH4Cl solution. The organic phase was separated, and concentrated to give the crude product, which was purified by preparative TLC to give (R)-6-allyl-6-(4-fluorophenyl)-3-((S)-1-(4-(1-methyl-6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-1,3-oxazinan-2-one (634 mg, 69%). 1H NMR (CDCl3): δ=1.52 (d, 3H), 2.16-2.35 (m, 3H), 2.52-2.64 (m, 2H), 2.94 (m, 1H), 3.61 (s, 3H), 5.00-5.11 (m, 2H), 5.66-5.74 (m, 2H), 6.64 (d, 1H), 6.90 (d, 2H), 7.02 (t, 2H), 7.11-7.14 (d, 2H), 7.25-7.28 (m, 2H), 7.41 (m, 1H), 7.53 (m, 1H).
