실험 절차

80 mL of reagent grade acetonitrile and 6.65 gm (0.025 mole) of 1-(1-butyl)-3-cyclohexylbarbituric acid were added to a dry 250 mL 3-neck round bottom flask equipped with a thermometer, pressure equalizing dropping funnel capped by a drying tube, nitrogen inlet and magnetic stirrer. The stirred solution was cooled to 2° C. in an ice bath. Then a solution of 5.75 gm (0.029 mole) of p-toluenesulfonyl azide in 20 mL of acetonitrile was added to the reaction flask. A solution of 3.20 gm (0.0317 mole) of triethylamine in 20 mL of reagent grade dichloromethane was placed in the dropping funnel and slowly added to the reaction flask, while keeping the temperature below 3° C. The flask temperature was kept below 3° C. for 1 hour. The stirred reaction flask was allowed to warm to room temperature (20° C.) and kept at room temperature for 12 hours.
