Reaction Steps

Ethyl 2-((N-(2,4,6-trichlorophenyl)sulfamoyl)amino)acetate (300 mg, 0.83 mmol), 2-methylenepropane-1,3-diol (73 mg, 0.83 mmol) and triphenylphosphine (544 mg, 2.08 mmol) were dissolved in anhydrous THF (30 mL) in a reactor, and then cooled down −20° C. after removal of air in the reactor by purging nitrogen gas. DIAD (420 mg, 2.08 mmol) was dropwisely added to the reaction mixture and agitated for 5 hr at room temperature. The resultant was concentrated under reduced pressure and purified by column chromatography (dichloromethane:hexane:ethyl acetate=5:4:1), finally yielding the title compound (305 mg, 89%, white solid). 1H NMR (300 MHz, CDCl3): δ 7.40 (s, 2H), 5.25 (s, 1H), 5.16 (s, 1H), 4.36 (s, 2H), 4.27-4.20 (m, 4H), 4.08 (s, 2H), 1.33-1.28 (t, 3H, J=7.1, 7.1 Hz).
