A process for producing a substituted aminoquinazolinone derivative represented by the formula (I), characterized by reducing a substituted iminoquinazolinone derivative represented by the formula (II) with hydrogen in the presence of a catalyst and either of a halogen compound and a sulfur compound; a substituted iminoquinazolinone derivative represented by the formula (II'), which is an intermediate in the production process; and a pest control agent containing the derivative of the formula (II') or a salt thereof as an active ingredient and a method of using the same (in the formulae, R represents hydrogen, formyl, (C1-C6) alkyl, (C1-C6) alkoxy (C1-C3)alkyl, (C1-C6) alkylsulfonyl, optionally substituted phenylcarbonyl, etc.; R1 represents an optionally substituted, 5- or 6-membered heterocycle having one to three heteroatoms selected among oxygen, sulfur, and nitrogen; R2 represents hydrogen or (C1-C3) alkyl; X and X' may be the same or different and each represents (C1-C6) haloalkyl, (C1-C6) haloalkoxy, etc.; n is an integer of 0 to 4; and n' is an integer of 1 to 4).
