Abstract

PURPOSE:To obtain the titled substance useful as a medicine in high yield and optical purity without varying steric configuration of starting compound, by reacting a methyl esterification reagent to a compound or its salt corresponding to the titled substance provided that the 5-carboxylic acid is in free state. CONSTITUTION:The titled substance can be produced either by reacting a 3, 5-dicarboxylic acid (3S)-3-(1-benzyl-3-pyrrolidinyl) ester derivative of formula (R' is ester residue easily eliminable by alkali hydrolysis treatment) directly with a methyl esterification reagent (e.g. diazomethane, methanol-hydrochloric acid, etc.) or by hydrolyzing the derivative under alkaline condition and reacting with a methyl esterification reagent.
