実験手順

A mixture of 2-((S)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)ethyl methanesulfonate (40 mg, 0.07 mmol), 1H-imidazol-2-amine (18 mg, 0.21 mmol), K2CO3 (29 mg, 0.21 mmol) in acetonitrile (4 mL) was heated to reflux overnight. The solvent was removed and the residue was partitioned between EtOAc and water. The aqueous layer was extracted with EtOAc and the combined organic layer was washed with brine, dried over Na2SO4, filtered and concentrated to give the crude product. It was purified by preparative HPLC to give (R)-6-(2-(1H-imidazol-2-ylamino)ethyl)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one (7 mg, 17%). LC-MS Method 3 tR=1.15, min, m/z=521; 1H NMR (CDCl3): 1.55 (m, 3H), 2.16-2.33 (m, 7H), 2.94 (m, 1H), 3.56 (m, 1H), 4.02 (m, 1H), 5.66 (m, 1H), 6.25 (m, 1H), 6.52 (m, 1H), 6.90 (m, 2H), 7.04 (m, 4H), 7.18 (m, 2H), 7.26 (m, 3H).
