실험 절차

To a stirred solution of 6-(hydroxymethyl)morpholin-3-one (Step-2 of Intermediate-9) (4.1 g, 31.29 mmole) in dichloromethane (25 mL), triethylamine (8.31 mL, 62.59 mmole) and TsCl (tosyl chloride) (6.56 g, 34.42 mmole) were added at 0° C. The reaction mixture was allowed to RT and further stirred overnight. Reaction mixture was diluted with dichloromethane (30 mL), and washed with brine solution (2×30 mL) and DM water, separated the organic layer, dried over Na2SO4, concentrated and further purified by flash chromatography (n-hexane:ethyl acetate, 1:4) to get the title compound as a white solid (3.8 gm). m/z 286.1
