Reaction Steps

To a solution of 2-nitroxyethylamine hydrochloride (659 mg, 4.62 mmol) in DMF (1 ml) was added sodium methoxide (227 mg, 4.20 mmol) followed by a solution of propyl N-cyano-5-ethylamino-3-pyridinecarboximidate (195 mg, 0.84 mmol) in DMF (1 ml) described in Example 10 of Experimental Example 1, and the mixture was stirred at room temperature for 3 hours. After the reaction was completed, the reaction mixture was evaporated under reduced pressure. The residue was suspended in water and extracted with chloroform. The chloroform layer was dried over anhydrous sodium sulfate and concentrated under redeuced pressure. The residue thus obtained was purified by silica gel column chromatography with a mixed solvent of methanol and chloroform as an eluent to give the title compound (208 mg, yield 89%) as colorless crystals.
