Method for preparing netupitant

The invention discloses a method for preparing netupitant, and belongs to the field of medicine compounds. The method includes the steps: performing condensation on 2-chloro-5-aminopyridine and formicacid; performing reduction, Boc protection and iodination; performing coupling and deprotection and then performing condensation on products and 2-(3, 5-bis-trifluoromethyl-phenyl)-2-methyl propionicacid; performing substitution on products and N-methylpiperazine to obtain the netupitant. The method has the advantages that the steps of processes for preparing the netupitant have fewer side effects, the method is high in yield and less in environmental pollution, after-treatment is simple, and the netupitant which is a product prepared by the aid of the method is high in purity and low in individual impurity content.
