Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a benzotriazole derivative useful as a rust preventing agent for copper and copper alloys or as a multifunctional type additive, etc., having oxidation preventing functions and photostabilizing functions for various kinds of polymers by reacting a Mannich base with a benzotriazole compound. SOLUTION: This compound represented by formula III is obtained by subjecting (A) a Mannich base represented by formula I [R is a (substituted) hydrocarbon; R1 and R2 are each H or an alkyl] and (B) a benzotriazole compound represented by formula II (R3 is H, CH3, Cl or the like) to a deaminating condensation reaction. The above reaction is preferably carried out by stirring the reactional mixture, e.g. without a solvent or in a suitable solvent at 80-150 deg.C under atmospheric pressure for 0.5-3 h and distilling off generated amines under a reduced pressure.
