Versuchsvorschrift
Proceeding in a manner similar to that described in part A of Example 8 above, 30.0 g of tetrachlorophthalic anhydride was interacted with 40.0 g of 1-(2-methoxyethyl)-2-methylindole in 75.0 ml of glacial acetic acid at approximately 110° C. for approximately one hour to obtain 55.83 g of 2-[1-(2-methoxyethyl)-2-methylindol-3-yl]carbonyl-3,4,5,6-tetrachlorobenzoic acid, (Formula V: R=CH3OC2H4 ; R1 =CH3 ; X=Cl4 ; Y=H), a pale yellow solid which melted at 182°-184° C. A significant infrared maximum appeared at 1750 (C=O; s).
