Procedure

Following a procedure similar to that described in Example 234 but using 2 g. of 3-(dimethylamino)-8-bromo-5-fluoro-1,2,3,4-tetrahydrocarbazole (Example 219), in 100 ml. of methyl alcohol, 1 g. of 10% palladium on charcoal and 1 g. of potassium hydroxide in 2 ml. of water there was obtained, after recrystallization from benzene, 1.3 g. of 3-(dimethylamino)-5-fluoro-1,2,3,4-tetrahydrocarbazole, m.p. 166°-168° C.
