The embodiment of the invention discloses 3-formyl-1H-substituted indazole and a preparation method thereof. The method comprises the step of taking 2-nitro-substituted toluene as a raw material to prepare a compound in a formula (VI). The method takes the 2-nitro-substituted toluene as the raw material to prepare the 3-formyl-1H-substituted indazole. The raw material used by the preparation method is cheap and easy to get; a product with relatively high purity can be obtained without column chromatography separation and purification; the method can be well applied to practical production andapplication. Further, reaction conditions required by a whole preparation process are mild; the use of reagents with strong reducibility or strong oxidability is not involved; the method is suitable for industrial production.
