β-AMINOETHYLCARBAZOLES

Abstract

1-, 2-, 3-, and 4-Acetylcarbazoles were converted to the corresponding carbazolylacetamides by the Willgerodt reaction. These were dehydrated with phosphorus oxychloride and the resulting 1-, 2-, 3-, and 4-cyanomethylcarbazoles reduced catalytically to the corresponding β-aminoethylcarbazoles. The syntheses of 1- and 4-acetylcarbazoles and 1-methoxy-4-β-aminoethyl-5, 6, 7, 8-tetra-hydrocarbazole are described.
