The invention relates to a preparation method for a tyrosine kinase inhibitor and a midbody thereof. According to the method, a compound 1,1-cyclopropane dicarboxylic acid diester is taken as a raw material, and 1-((4-((6,7-dimethoxy quinoline-4-yl) oxy) phenyl) carbamoyl) cyclopropane formic ether is prepared by two ways and reacts with p-fluoro aniline after being hydrolyzed so as to prepare Cabozantinib. The reaction conditions of the preparation method are mild, the synthesis cost is lowered, and the preparation method is simple and convenient to operate and is applicable to industrial production.
