Procedure

By following the method of Example 2, methyl N-(2-hydroxyethyl)-3-carbomethoxy-4-methylpyrrole-2-acetate (IV, R = CH3) is converted into methyl N-(2-mesyloxyethyl)-3-carbomethoxy-4-methylpyrrole-2-acetate and then cyclized with sodium hydride in dimethylformamide, in accordance with the method of Example 8, to afford dimethyl 1,2-dihydro-6-methyl-3H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylate.
