The invention discloses a method for preparing 2-amino-4-methyl-1-propyl-1H-pyrrole-3-carbonitrile, and belongs to the technical field of organic synthesis. The preparation method comprises the following steps: taking epoxypropane and n-propylamine as raw materials; after hydrogen on a nitrogen atom is protected, oxidizing, removing a protecting group, and cyclizing with malononitrile to obtain the 2-amino-4-methyl-1-propyl-1H-pyrrole-3-carbonitrile. The method has the advantages of high product yield, high purity, accessible raw materials and simple operation, and is beneficial to industrialproduction.
