実験手順

(S)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-6-(2-hydroxyethyl)-1,3-oxazinan-2-one (50 mg, 0.11 mmol) was dissolved in CH2Cl2 (3 mL), followed by the addition of TEA (1 mL) and 4-nitrophenyl carbonochloridate (88 mg, 0.44 mmol). The mixture was stirred at rt overnight. Aqueous ammonia (2 mL) was added and the mixture was stirred at rt for 3 h. After separation of the water layer, the organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo to give the crude product, which was purified by preparative TLC to afford 2-((S)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)ethyl carbamate (20 mg, 35%). LC-MS Method 3 tR=1.36, min, m/z=499; 1H NMR (CDCl3): 1.48 (m, 3H), 2.14-2.33 (m, 5H), 2.91 (m, 1H), 3.42 (s, 1H), 3.95 (m, 1H), 4.07 (m, 1H), 4.62 (s, 2H), 5.61 (m, 1H), 6.79-7.01 (m, 6H), 7.23 (m, 5H).
