Participants

Reaction Steps

To a solution of N,N′-bis[2-(3,4,5-triethoxyphenyl)-5-pyridyl]-N,N′-dimethylethylenediamine (123.0 mg, 0.186 mmol) in methanol (3.0 mL) was added a 1.0 M solution of methanesulfonic acid in methanol (0.38 mL, 0.38 mmol), and the reaction mixture was concentrated under reduced pressure. Chloroform-diethyl ether was added to the residue and the resulting precipitate was collected by filtration to afford the title compound as a yellow crystalline powder [melting point: 237.0° C. (decomposed)](110.0 mg, yield: 70%).
