PROBLEM TO BE SOLVED: To provide a method for producing a silylated aniline compound, capable of producing the subject derivative useful as an intermediate for synthesizing, etc., at an increased reaction rate in a high yield, by reacting a specific aniline derivative with a specified halogenated organosilicon compound in the presence of a tertiary amine containing diazabicycloundecene in a prescribed amount. SOLUTION: This method for producing a silylated aniline compound comprises subjecting an aniline derivative expressed by formula I [R1 to R5 are each H, a halogen, a 1-6C (substituted)momovalent hydrocarbon; R6 is a 1-6C (substituted)momovalent hydrocarbon] and a halogenated organosilicon compound expressed by formula II [R7 to R9 are each a 1-6C (substituted) momovalent hydrocarbon; X is a halogen] to dehalogenating hydrogenation reaction in the presence of a tertiary amine containing 1,8-diaza- bicyclo[5,4,0]undec-7-ene (DBU) in an amount of 0.5-20 mol% as a base to form a silylated aniline compound of formula III. Triethylamine containing DBU in an amount of 0.5-20 mol% is preferably used as the base.
