Reaction Steps

To ethyl 2-(4-methylene-1,1-dioxido-6-(2,4,6-trichlorophenyl)-1,2,6-thiadiazinan-2-yl)acetate (305 mg, 0.74 mmol) in THF (10 mL) and MeOH (10 mL), was added LiOH monohydrate (155 mg, 3.69 mmol) in water (3 mL) and agitated for 5 hr at room temperature. After addition of ethyl acetate (30 mL) and water (30 mL), pH of the resultant was adjusted to 3 with 1 N HCl and extracted to the organic layer. The resultant was dried over MgSO4, concentrated under reduced pressure, and crystallized with ethyl acetate (1 mL) and hexane (10 mL), giving the compound of interest (253 mg, 89%, white solid). 1H NMR (300 MHz, CDCl3): δ 7.42 (s, 2H), 5.26 (s, 1H), 5.16 (s, 1H), 4.41 (s, 2H), 4.33 (s, 2H), 4.09 (s, 2H).
