実験手順

0.17 Mole (35.7 g) of 2,3-dihydro-5,7-dinitrobenzofuran, prepared according to Chatelus Ann. Chim. [12], 4,505-547 (1949), is suspended in 350 ml of 20% strength ammonia solution and 220 ml of formamide. After 8 hours' heating at 110° C., a further 100 ml of 20% strength ammonia solution are added. Heating is maintained for 4 hours. When the reaction medium is cooled, the expected product precipitates.
