Procedure

To a solution of 1,4-bis[5-(3,5-dimethylphenyl)-2-pyridyl]hexahydro-1,4-diazepine (83.0 mg, 0.170 mmol) in methanol (5.0 mL) was added a 1.0 M aqueous methanesulfonic acid (0.37 mL, 0.37 mmol), and the mixture was concentrated under reduced pressure. Ethanol (5.0 mL) was added to the residue, and the resulting mixture was concentrated under reduced pressure. The residue was recrystallized from ethanol-diethyl ether-hexane to yield the title compound as colorless needles [melting point: 188.0° C. (decomposed)](101.0 mg, yield: 86%).
