Procedure
To a solution of N,N′-bis[2-(3,5-dimethoxy-4-propoxyphenyl)-5-pyridyl]-N,N′-dimethylethylenediamine (124.0 mg, 0.196 mmol) in methanol-chloroform (1:2, 3.0 mL) was added a 1.0 M aqueous methanesulfonic acid (0.41 mL, 0.41 mmol), and the reaction mixture was concentrated under reduced pressure. Ethanol (5.0 mL) was added to the residue, and the mixture was concentrated under reduced pressure. The residue was recrystallized from ethanol-diethyl ether-hexane to afford the title compound as yellow a crystalline powder (melting point: 241.0-243.0° C. ) (91.0 mg, yield: 56%).
