Synthesis method of lapatinib intermediate

The invention discloses a synthesis method of a lapatinib intermediate, and belongs to the technical field of organic synthesis. The method comprises the following steps: performing carboxyl protection on p-fluorobenzoic acid serving as a raw material and adding acetyl at an ortho-position to obtain a compound IV, performing chiral reduction on the compound IV to obtain a compound V with S configuration, performing Mitsunobu reaction on the compound V and 3-hydroxy-2-nitropyridine to obtain a compound VI with R configuration, performing reaction on the compound VI and hydrochloric acid methanol to obtain a compound VII, and performing recrystallization to obtain the compound VII. and finally, performing nitro-reduction to obtain products. The method has the advantages that the initial raw materials are cheap and easy to obtain (the price of p-fluorobenzoic acid is far lower than that of the raw materials in the prior art), the stereoselectivity is good, chiral resolution is not needed, the total yield is high (the existing yield is about 20%, and the patent is larger than 40%), and a feasible scheme is provided for lapatinib process research.
