Reaction Steps

A solution of 2-(2-hydroxyethyl)-4-nitro-2H-1,2-benzisothiazol-3-one 1,1-dioxide (100 mg, 0.37 mmol) and ethanolamine (24 mg, 0.39 mmol) in THF (5 ml) was allowed to stand at 20-25° for 3 days. After removal of THF under reduced pressure, the residue was recrystallized from MeOH-EtOAc-hexane to give 112 mg (91%) of product, m.p. 176.5-177.5°.
