Method for synthesizing lapatinib or intermediate thereof

The invention relates to a method for synthesizing lapatinib or an intermediate thereof. The method for synthesizing the intermediate comprises the steps as follows: under the condition that a catalytic quantity of a catalyst exists in a solvent, 4-amino-5-(4-(3-chloro-4-(3-fluorobenzyloxy) phenylamino)-quinazoline reacts with furfural for preparation of 5-(4-(3-chloro-4-(3-fluorobenzyloxy) phenylamino)-quinazoline-6-yl)furyl-2-carboxaldehyde hydrochloride, and the intermediate is prepared. The invention further relates to a method for synthesizing lapatinib and/or salt of lapatinib, the intermediate of lapatinib and/or pharmaceutically acceptable salt of the intermediate, and the method is performed with the intermediate which is synthesized by the previous method. The method has the advantages that steps are simplified, a reagent is cheap, available and high in use ratio, pollution from heavy metal is avoided, and requirements for reaction conditions/operation are relatively low and/or the yield is high.
