2,3-Dihydro-1H-pyrrolo[1,2-a]pyrrole-1-carboxylic acid is dissolved in methanol containing a small amount of concentrated hydrochloric acid. The resulting solution is heated to reflux, and then cooled. The title compound is isolated by rotary evaporation of the solvent under reduced pressure, and may be purified by chromatography on silica gel with hexane/ethyl acetate as eluent.
