Participants

Reaction Steps

To a solution of N,N′-bis[2-(4-ethoxy-3,5-dimethoxy-phenyl)-5-pyridyl]-N,N′-dimethylethylenediamine (133.0 mg, 0.220 mmol) in methanol (2.0 mL) was added a 1.0 M aqueous methanesulfonic acid solution (0.44 mL, 0.44 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 methanol-diethyl ether to afford the title compound as a yellow crystalline powder (melting point: 232.0-234.0° C. )(120.0 mg, yield: 54%).
