실험 절차

To a solution of 2-((S)-3-((S)-1-(4-bromophenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)ethyl-methanesulfonate (360 mg, 0.75 mmol) and K2CO3 (207 mg, 1.5 mmol) in acetonitrile (10 mL) was added isothiazolidine 1,1-dioxide (121 mg, 4.6 mmol), and the mixture was refluxed overnight. The mixture was filtered and the filtrate was concentrated to give the crude product, which was purified by preparative HPLC to afford compound (S)-3-((S)-1-(4-bromophenyl)ethyl)-6-(2-(1,1-dioxo-isothiazolidin-2-yl)ethyl)-6-phenyl-1,3-oxazinan-2-one (2.43 mg, 1%). LC-MS Method 2 tR=1.37 min, m/z=509, 507. 1H NMR (CDCl3): 1.48 (t, 3H), 2.05-2.41 (m, 7H), 2.71-2.92 (m, 2H), 3.11 (m, 3H), 3.21 (m, 2H), 5.58 (m, 1H), 6.73 (d, 2H), 7.18 (m, 1H), 7.23 (m, 3H);7.35 (m, 3H).
