الإجراء التجريبي

0.29 Mole (60.9 g) of 2,3-dihydro-5,7-dinitrobenzofuran is added in small portions at room temperature to 122 ml of 2-aminoethanol. After the addition is complete, the reaction medium is brought for 15 minutes to 95° C. 500 ml of water are added; after the mixture is cooled, the expected product is drained, and this, after being made into a paste in water and recrystallized from 75 ml of 96° strength ethanol, melts at 115° C.
