Participants

Reaction Steps

To 5,6-difluoro-2-methyl-1-(ρ-methylsulfinylbenzylidene)-indene-3-aceticacid (0.005 mole) in acetone (15 ml.) is added, slowly with stirring, m-chloroperbenzoic acid (0.005 mole). The mixture is heated and evaporated to near dryness at 40°. The solid is washed with boiling water (4×50 ml.) and dried yielding 5,6-difluoro-2-methyl-1-(ρ-methylsulfonylbenzylidene)-indene-3-acetic acid, M.P. 228-230°. (R1 =hydrogen; R2 =CH3 ; R3 =5-fluoro; R4 =6-fluoro; R5 =CH3 --SO2 --).
