Preparation of twelve 1-methyl-2-formyl-5-substituted pyrroles (2a-1), with five of them as new compounds, is described. Their derivatives, i.e., 1-methyl-2-formyl-5-substituted pyrrole phenyl hydrazones (3a-1) and 1-methyl-2-formyl-5-substituted pyrrole (4-nitrophenyl) hydrazones (4a-1) are all new compounds. They have also been prepared and further identified.
