実験手順
3-(Dimethylamino)-8-bromo-1,2,3,4-tetrahydrocarbazole (18.8 g.) (Example 211) and 17.5 g. of cuprous cyanide in 150 ml. of dimethylformamide was heated under reflux for four hours. The warm reaction mixture was poured into a solution of 200 ml. of ethylenediamine in 400 ml. of water. This was mixed thoroughly and extracted several times with chloroform. The chloroform layer was separated and washed with a dilute solution of ethylenediamine, water, saturated salt solution, and evaporated to dryness to give, after recrystallization from benzene, 6.9 g. of 3-(dimethylamino)-8-cyano-1,2,3,4-tetrahydrocarbazole, m.p. 177°-179° C.
