실험 절차

2'-[(methylsulfinyl)-acetyl]benzanilide (7 g) is refluxed in benzene containing 1 equivalent of trifluoroacetic acid for 1 hour. The solvents are removed under reduced pressure to give an oil which crystallizes on standing. Recrystallization from ethyl acetate gives 1-benzoyl-2-(methylthio)-3-indolinone (4.5 g 67%) m.p. 126°-128° C.
