Participants

Reaction Steps

To a mixture of 120 g (0.42 mole) of ethyl 5-(4-chlorophenyl)-2-furimidate hydrochloride in 700 ml of absolute ethanol was added dropwise 62 ml (0.46 mole) of triethylamine at a temperature of 2°-4° while under a nitrogen atmosphere. To this stirring mixture was added portionwise 28 g (0.47 mole) of formic acid hydrazide while maintaining the temperature at 4°-7° by means of an ice bath. The mixture was kept at 5°-7° for 15 minutes, allowed to warm to 23° over a 21/2 hour period, cooled to 10°, filtered, and washed in stirring S.D.A #32 to yield 52 g (47%). An analytical sample was prepared by drying a sample in a vacuum pistol with refluxing chloroform, m.p. 155°-157° (Mel-Temp).
