Abstract
A process for producing indolylacetic acid derivatives represented by the formula **(See formula)** where each X1 and X2 is a member selected from the group consisting of oxygen and methylene; A is a member selected from the group consisting of unsubstituted saturated hydrocarbon chains having up to 5 carbon atoms, unsubstituted unsaturated hydrocarbon chains having up to 5 carbon atoms, and substituted unsaturated and substituted saturated hydrocarbon chains having up to 5 carbon atoms carbon in which the substituent is a member selected from the group consisting of halogen and phenyl; m is 0 or 1; n is 1 or 2; each R1 and R2 is a member selected from the group consisting of hydrogen and alcoholic having up to 4 carbon atoms; R3 is a member selected from the group consisting of alcohol having up to 4 carbon atoms, cycloalcohyl having 3 to 7 carbon atoms, aryl unsubstituted or substituted by lower alcohol, lower alkoxy, lower alcoholylthio, nitro, cyano, trifluoromethyl, methylenedioxy, ethylenedioxy or halogen, each of said substituents being alcoholic, alkoxy and alcoholylthio up to 4 carbon atoms, monoalicyclic or pilialicyclic groups unsubstituted or substituted by halogen, alcoholic or phenyl, or benzene ring condensed, saturated or unsaturated, or a alcohol group substituted by said alicyclic group, or a 5- or 6-membered heterocyclic ring group unsubstituted or substituted by methyl, ethyl or halogen containing oxygen, sulfur or nitrogen atoms; R4 is a member selected from the group consisting of alcohol having up to 4 carbon atoms, hydrogen or M radical (where M is a cation), characterized by treating an N1-acylated compound represented by the formula **(See formula)** where X1, X2, A, m, n and R3 are the same as defined above, and B is a member selected from the group consisting of (see formula) (in which Z is a nitrogen protecting system comprising at least one easily separable group), with an aliphatic acid derivative represented by the formula **(See formula)** where R1, R2 and R4 are the same as defined above.
