Methanesulfonic Acid → HCID 22485505, compound

Participants

Reaction Steps

To a solution of N,N′-diethyl-N,N′-bis[2-(4-isopropoxy-3,5-dimethoxyphenyl)-5-pyridyl]-1,3-propanediamine (78.0 mg, 0.110 mmol) in methanol-chloroform (2:1, 3.0 mL) was added a 1.0 M aqueous methanesulfonic acid (0.24 mL, 0.24 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-hexane to yield the title compound as yellow flakes (melting point: 173.0-175.0° C.) (66.0 mg, yield: 66%).
