Isopropyl N-cyano-4-pyridinecarboximidate → HCID 19734537, compound

Participants

Reaction Steps

Isopropyl N-cyano-4-pyridinecarboximidate (0.31 g, 1.6 mmol) was dissolved in methanol (15 ml), and 1-methyl-2-(4-nitrophenyl)-2-nitroxyethylamine nitrate (0.50 g, 1.8 mmol) and sodium methoxide (0.09 g, 1.7 mmol) were added. The mixture was stirred at room temperature for 16 hours. After the reaction was completed, the reaction solution was concentrated under reduced pressure, and the residue was extracted with chloroform (50 ml×3). The chloroform layer was washed with water (100 ml), dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue thus obtained was subjected to chromatography on a silica gel column (WAKO GEL C-200, 30 g) eluting with chloroform-methanol (60:1). The eluted fractions were concentrated under reduced pressure and crystallized from diethyl ether to give the title compound (0.03 g, 0.08 mmol, yield: 5%) as colorless crystals.
