실험 절차

To a solution of (S)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-6-(2-hydro-xyethyl)-1,3-oxazinan-2-one (100 mg, 0.22 mmol) in THF (5 mL) was added NaH (30 mg, 1.10 mmol) at 0° C. After stirring for 1 h, allyl bromide (79 mg, 0.66 mmol) was added, and the mixture was stirred at rt overnight. The reaction was quenched with water, and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated. The residue was purified by preparative TLC to give (S)-6-(2-(allyloxy)ethyl)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one (100 mg, 92%) 1H NMR (CDCl3): 1.47-1.59 (d, 3H), 2.05-2.15 (m, 2H), 2.21-2.38 (m, 3H), 2.88-2.93 (m, 1H), 3.12-3.19 (m, 1H), 3.52-3.59 (m, 1H). 3.62-3.85 (m, 2H), 5.03-5.18 (m, 2H), 5.61-5.69 (m, 1H), 5.71-5.81 (m, 1H), 6.81-6.92 (m, 3H), 6.92-7.01 (m, 2H), 7.13-7.20 (m, 4H), 7.21-7.26 (m, 3H).
