| Product | 5,6-Dihydro-N,N-dimethyl-4H-pyrrolo(3,2,1ij)quinolin-5-amine | HCID 11469718 | — |
Reaction Steps
This compound was prepared by following the procedure of Example 18, but substituting methyl 7-(bromomethyl)-1H-indole-1-carboxylate for t-butyl 4-(bromomethyl)-1H-benzimidazole-1-carboxylate and diethyl (dimethylamino)malonte for diethyl (dipropylamino)malonate. The bulk of the product was converted to the maleate salt, mp 114°-115° C. from THF/ether.
