Reaction Steps

8-Fluoro-1,2,3,9-tetrahydro-9-methyl-3-[(5-methyl-1H-imidazol-4-yl) methylene]-4H-carbazol-4-one (1.5 g) was dissolved in ethanol (50 ml) and added to a suspension of 5% palladium on charcoal (200 mg) in ethanol (ca. 50 ml), and the resulting mixture was hydrogenerated at room temperature and atmospheric pressure until hydrogen uptake had ceased. The mixture was filtered, and the filtrate was evaporated in vacuo to give the title compound (1.5 g), m.p. 189°-191° (decomp.), t.l.c. (System A 100:8:1), Rf 0.43.
