Pyrrolidine derivative, production method therefor, mse-type zeolite, and production method therefor

A method for producing a pyrrolidine derivative comprising:

• a first step of preparing N,N′-dialkylbicyclo[2.2.2]oct-7-ene-2,3;5,6-tetracarboxydiimide or N,N′-dialkylbicyclo[2.2.2]octane-2,3;5,6-tetracarboxydiimide;
• a second step of reacting the N,N′-dialkylbicyclo[2.2.2]oct-7-ene-2,3;5,6-tetracarboxydiimide or the N,N′-dialkylbicyclo[2.2.2]octane-2,3;5,6-tetracarboxydiimide with a reducing agent to obtain N,N′-dialkylbicyclo[2.2.2]oct-7-ene-2,3;5,6-dipyrrolidine and/or N,N′-dialkylbicyclo[2.2.2]octane-2,3;5,6-dipyrrolidine;
• and
• a third step of reacting the N,N′-dialkylbicyclo[2.2.2]oct -7-ene-2,3;5,6-dipyrrolidine and/or the N,N′-dialkylbicyclo[2.2.2]octane-2,3;5,6-dipyrrolidine with an alkyl halide to obtain an N,N,N′,N′-tetraalkylbicyclo[2.2.2]oct-7-ene -2,3;5,6-dipyrrolidinium salt and/or an N,N,N′,N′-tetraalkylbicyclo[2.2.2]octane-2,3;5,6-dipyrrolidinium salt,
• wherein the method satisfies at least one of the following condition (1) or (2),
• the condition (1) being that in the second step, the reducing agent comprises at least one selected from the group consisting of sodium bis(2-methoxyethoxy)aluminum hydride, lithium triethylborohydride, diisobutylaluminum hydride, diborane, lithium borohydride, and sodium borohydride, and
• the condition (2) being that in the third step, the alkyl halide is reacted in the presence of an organic solvent in a molar ratio of 13 times or less relative to the N,N′-dialkylbicyclo[2.2.2]oct-7-ene-2,3;5,6-dipyrrolidine and/or the N,N′-dialkylbicyclo[2.2.2]octane-2,3;5,6-dipyrrolidine.
