Ammonia → HCID 178444270, compound

Participants

Reaction Steps

In 20 ml of N,N-dimethylformamide, 7 g of the 1-(trans-4-pentylcyclohexyl)-4-(4-bromophenyl)dihydrobenzene, which had been obtained in Example 18, were dissolved, followed by the addition of 2.0 g of cuprous cyanide. The resulting mixture was reacted for 6 hours at reflux temperature. After the completion of the reaction, aqueous ammonia was added to the reaction mixture, followed by extraction with toluene. The extract was washed with aqueous ammonia and then with saturated NaCl. Anhydrous sodium sulfate was thereafter added to dry the extract. The toluene was distilled off under reduced pressure. The reaction product so obtained was recrystallized from ethanol, whereby 0.7 g of 1-(trans-4-pentylcyclohexyl)-4-(4-cyanophenyl)dihydrobenzene was obtained.
