97.43% With ethylenediamine In ethanol; water; N,N-dimethyl-formamide Results and Discussion 3,7-Dicyano-dibenzofuran 19. A suspension of 3,7-dibromo-dibenzofuran (18, 10.27 g, 31.51 mmol) and copper(I) cyanide (8.23 g, 94.5 mmol) in DMF (80 mL) was refluxed under N2 for 6 h. The reaction mixture was poured into ice-water (300 mL). The precipitated solid was collected and stirred for 5 h in a solution of ethylenediamine (50 mL) in water (300 mL). The solid was filtered off, washed with water, then stirred in 10% sodium cyanide solution (100 mL) for 4 h. The solid was further purified by suspension in hot ethanol (100 mL) to give a pale yellow powder (6.69 g, 97.43%): mp 322-325° C.
