A method for producing a norbornene derivative, comprising:
a first step of forming a Mannich base by reacting a carbonyl compound and an amine compound with each other in an acidic solvent, to thereby obtain a reaction liquid comprising the Mannich base in the acidic solvent,
the acidic solvent comprising a formaldehyde derivative and 0.01 mol/L or more of an acid represented by the formula: HX (In the formula, X represents F or the like),
the carbonyl compound being represented by any of the following general formulae (1) to (3):
[in formulae (1) to (3), R1, R2, R3, R4, R5, and R6 each independently represent a hydrogen atom or the like, and n represents an integer of any of 0 to 4],
the amine compound being represented by the following general formula (4):
[in the formula (4), R7S each independently represent a linear chain saturated hydrocarbon group having 1 to 20 carbon atoms or the like, and X- represents F- or the like],
the Mannich base being represented by any of the following general formulae (5) to (7):
[R1, R2, R3, R4, R5, R6, and n in the formulae (5) to (7) have the same meanings as those of R1, R2, R3, R4, R5, R6, and n in the formulae (1) to (3), and R7 and X- in the formulae (5) to (7) have the same meanings as those of R7 and X- in the formula (4)] and
a second step of reacting the Mannich base and a diene compound with each other by adding an organic solvent, a base in an amount of 1.0 to 20.0 equivalents to the acid, and the diene compound to the reaction liquid, and then heating the reaction liquid, to thereby form a norbornene derivative,
the diene compound being represented by the following general formula (8):
[in the formula (8), R8 represents a hydrogen atom or the like],
the norbornene derivative being represented by any of the following general formulae (9) to (11):
[R1, R2, R3, R4, R5, R6, and n in the formulae (9) to (11) have the same meanings as those of R1, R2, R3, R4, R5, R6, and n in the formulae (1) to (3), and R8 in the formulae (9) to (11) has the same meaning as that of R8 in the formula (8)].
