This compound can be obtained in tvvo different ways: 1) The reaction of 3-bromophthalide (A) with 5-methoxy-2-methyl-1H-indole-3-acetic acid (I) previously salified with triethylamine in refluxing acetone gives (?-1,3-dihydro-3-oxo-1-isobenzofuranyl-5-methoxy-2-methyl-1H-indole-3-acetate (II). Compound (II) is salified with sodium hydride and then acylated with p-chlorobenzoyl chloride (B). 2) By condensation of the organic salt of 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid (III) with 3-bromophthalide (A).
