2-Methoxyphenethylamine → N-cyano-N'-[2-(2-methoxyphenyl)ethyl]-4-pyridinecarboximidamide

Participants

Reaction Steps

Isopropyl N-cyano-4-pyridinecarboximidate (0.50 g, 2.6 mmol) was dissolved in methanol (10 ml), and 2-(2-methoxyphenyl)ethylamine (0.44 g, 2.9 mmol) was added. The mixture was stirred at room temperature for 1 hour. After the reaction was completed, the reaction solution was concentrated under reduced pressure. The residual concentrate was subjected to chromatography on a silica gel column (WAKO GEL C-200, 40 g) eluting with chloroform-methanol (100:1). The eluted fractions were concentrated under reduced pressure and crystallized from chloroform-diethyl ether to give the title compound (0.45 g, 1.6 mmol, yield: 61%) as colorless crystals.
