실험 절차

528 mg of 2,6-dichloroisonicotinaldehyde (this compound was prepared by the method described in J. Chem. Soc., Chem. Commun., 1998, 1567-1568) was dissolved in 10 ml of methanol, and 586 mg of p-toluenesulfonyl methyl isocyanide and 415 mg of potassium carbonate ware added, and the mixture was stirred at 50° C. for 30 minutes. The reaction solution was concentrated, and then diluted with ethyl acetate, and the organic layer was washed with a saturated aqueous solution of sodium bicarbonate and brine, and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 630 mg of the objective compound as white powder.
