الإجراء التجريبي

A mixture of 11.1 g (0.1 mole) of furamide, 20.8 g (0.1 mole) of phosphorus pentachloride and 150 ml of AR carbon tetrachloride was heated at 70° for 30 min. or until the HCl gas evolution had ceased. Cooled to 30° and 4.7 g (0.1 mole) of 97% formic acid was added dropwise. Stirring was continued for 45 min., before filtering. The product was washed with AR carbon tetrachloride and air-dried to give 17.8 g, m.p. softens 83°, melts 93°-112°.
