Procedure

Isopropyl N-cyano-3-pyridinecarboximidate (0.60 g, 3.2 mmol) was dissolved in methanol (10 ml), and 2-(4-chlorophenyl)ethylamine (0.55 g, 3.5 mmol) was added. The mixture was stirred at room temperature for 2.5 hours. 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, 50 g) eluting with chloroform-methanol (100:1). The eluted fractions were concentrated under reduced pressure, and the concentrated residue thus obtained was further crystallized from methanol-diethyl ether to give the title compound (0.71 g, 2.5 mmol, yield: 79%) as colorless powder.
