The invention provides a hydrogenation reduction preparation process of an apatinib intermediate, and relates to the technical field of pharmaceutical chemicals. According to the preparation process of the apatinib intermediate, 1-(4-nitrophenyl) cyclopentane-1-formonitrile and H2 are subjected to a hydrogenation catalytic reaction to prepare 1-(4-aminophenyl) cyclopentane formonitrile, and a used catalyst is a triphenylphosphine sulfide / raney nickel complex. The 1-(4-aminophenyl) cyclopentane formonitrile is prepared by efficiently and highly selectively catalyzing the hydrogenation of 1-(4-nitrophenyl) cyclopentane-1-formonitrile by taking a complex obtained by carrying out coordination complexation on triphenylphosphine sulfide and Raney nickel as a catalyst, and the reaction yield is high, the content of a byproduct is low, and the reaction conditions are mild. Meanwhile, the metal coordination catalyst reduces the consumption of nickel metal, greatly simplifies the process, saves the production cost, and has important industrial application value; the catalyst can be cyclically applied in a high-activity manner, and the catalyst does not need to be supplemented in the cyclically applied process.
