Reaction Steps
By the procedure of Example Al, but substituting an equivalent of dimethylformamide dimethylacetal for the dimethylacetamide dimethylacetal, using first methylene chloride and then 7.5% ethyl acetate in methylene chloride in chromatography and recrystallization from ether-pentane, 1-(3-chlorophenyl)-2(1H,3H)-indolone (10 g, 0.041 mole) was converted to title product, 3.73 g, m.p. 116°-118°.
