Procedure

Similarly, substituting for the dimethyl 2,3-dihydro-1H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylate of part A of this Example, diethyl 2,3-dihydro-1H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylate, and similar di(lower alkyl) 2,3-dihydro-1H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylates, one obtains 2,3-dihydro-1H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylic acid.
