実験手順

To a solution of 2-((S)-3-((S)-1-(2′,4′-difluorobi-phenyl-4-yl)ethyl)-6-(4-fluorophenyl)2-oxo 1,3-oxazinan-6-yl)ethyl methanesulfonate (58 mg, 0.11 mmol) in anhydrous MeOH was added 2-amino-ethanol (54 mg, 0.88 mmol). Then the reaction mixture was refluxed overnight. When the reaction was over, solvent was removed in vacuo. The residue was purified by preparative HPLC to give (R)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-6-(2-(2-hydroxyethylamino)ethyl)-1,3-oxazinan-2-one (2 mg, 3%). 1H NMR (CDCl3): 1.53 (m, 3H), 2.25-2.36 (m, 4H), 2.51 (m, 1H), 2.87-3.24 (m, 5H), 3.75-4.02 (m, 2H), 5.60 (m, 1H), 6.85-6.96 (m, 2H), 6.96-7.10 (m, 4H), 7.22 (m, 2H), 7.38 (m, 4H).
