Method for preparing disperse red SBWF

The invention relates to a preparation method of disperse red SBWF. The preparation method comprises the following specific steps: by using 4-(tetrahydrofuran-2-methoxy)-benzaldehyde and trichloromethane as raw materials, carrying out carbene reaction under the action of a phase transfer catalyst to prepare intermediate 4-(tetrahydrofuran-2-methoxy) mandelic acid; and carrying out condensation andoxidation of 4-(tetrahydrofuran-2-methoxy) mandelic acid and 5-hydroxy-3-phenyl-3H-benzofuran-2-one to prepare the target product 3-phenyl-7-(4-(tetrahydrofuran-2-methoxy) phenyl)-benzodifuran-2, 6-dione. The preparation method has the advantages of simplicity in operation, mild reaction conditions, environmental friendliness and the like, and has good industrial application value.
